The Spam Experiment

In common with about everyone else on the net I get spam emails flooding into my email box every day. In a dizzyingly short period of time I have the opportunity of achieving a larger penis along with enormous breasts, I can become a millionaire overnight, presumably the day after fixing my credit rating, I can take viagra to last longer with the woman that I hypnotised into bed, while watching nubile young ladies perform for me on webcam by paying them via the credit card that I've just been guaranteed. Spam is that amazing creation that allows all the crackpots, the fraudsters and the cheats to not only knock on our doors but to walk right in and make themselves at home.
I've read a lot about how to stop spam - how to filter it out, how to report the people who do it, how to blacklist the people who send it to you, and how to track them down to real accounts - and all very interesting it is too. However, despite having spent some time looking around on the Web, I've not really seen anything that looks at how you actually get it in the first place. Yes, I know that spammers get your email address, which then gets added to lists and sold onto other disreputable people who fill your mailbox with junk, but I was interested in seeing how they got the email address in the first place. How widely spread would your address need to be in order to catch the attention of the spammers? As it turns out, not very widely spread at all, as we shall see.
I decided to create some email accounts, and then publicise this at various places on the web. I chose to use Hotmail for this purpose for a number of reasons - it was quick and easy to create accounts, Hotmail accounts are very common (who doesn't have one?), I could inspect them whenever and wherever I chose and it also meant that I wouldn't be getting any more spam than necessary in my own email box.
I created a number of accounts that would be used for different purposes:
I could have chosen many other places to publicise different addresses - there are plenty of other groups other than those provided by Yahoo! for example, and I also wasn't taking into account the spam that arises as a result of visiting particular websites. However, odd though it may seem, I do have a life and I wanted to make the most of the short summer months in England. Besides, I have clients who need work to be done for them, so I drew a halt at that point.
Having set up the accounts, registered with the various services mentioned, and posted one single copy of each email address I then sat back and waited to see if my spam traps would work. I didn't have long to wait...
I had my first spam message inside a couple of hours, and it was to the email account I used to opt-out of mailings. To be honest, this wasn't exactly a surprise to me, and I was soon to discover opting out of a mailing list is like wandering into the rapids just wearing a small life protector - you're going to get swept along very quickly and end up drowning! Initially I was quite fascinated to see how much spam I was getting, and checked the accounts a couple of times a day, but after a while the thrill began to pall - after all it does get a bit depressing to realise that so many people think I've got a small penis and no money in my bank account! Eventually I ended up checking them once every couple of weeks, just to make sure that they were still active.
I was also very wryly amused at how many of the spam emails assured me that I was only getting their messages because I'd visited their sites and requested to be kept informed about their various products - in fact once or twice I almost doubted myself and thought about checking to see if there was anything like sleep-computing! However, I was fairly convinced that even if I had been computing in my sleep I wouldn't be visiting sites about septic tanks, of which I seemed to get a lot of emails, entreating me to purchase one and improve my lifestyle. Quite how a septic tank is going to improve my lifestyle I'm none too sure - after all, 'Come up and see my septic tank' isn't exactly going to work wonders is it.
Eventually however all good things must come to an end. Summer began to fade and autumn decided it was time to come out and romp and play, and I too decided that after about 10 weeks it was time to draw my spam experiment to an end. I was then faced with the enormity of going through each account in turn and adding up columns of figures.
Rather than simply add up the number of emails I had received it had been suggested to me that it would be interesting to to classify them somehow. This appealed to me - after all, my background is that of a librarian, so a little bit of classification couldn't come amiss. It didn't take long to work out some major categories - I just had to look at the titles of the emails that I'd been sent. Regretfully I decided that I didn't have enough time to open each one in turn to read the contents - I would simply have to assign a category based either on the subject of the email or if that wasn't always clear, on the name of the sender, which usually was. Faced with an email with the subject 'come and see my website' wasn't necessarily very clear, but when it had been sent by 'SexySuzie' it didn't take too much working out! However, in cases where it really wasn't clear the email was assigned to the wonderful 'miscellaneous' category.
The categories that I used were as follows:
Of course, I could have broken these categories down even further, but as I said earlier, I have a life. They're good enough for me, and if you don't like them you're more than welcome to try your own spam experiment.
For those of you without a morbid interest in figures, the two outright 'winners' are money and sex. No big surprise there, but if you'd been expecting one I have to tell you that you don't know much about humankind. The actual breakdown is as follows:
|
Financial |
231 |
|
Pornographic |
185 |
|
Health |
108 |
|
Misc. |
57 |
|
Hardware/ |
41 |
|
Attracting a partner |
40 |
|
Getting a degree |
40 |
|
Holidays |
6 |
I was slightly surprised at the results, since I'd always assumed that I got more pornographic spam than anything else (who knows - maybe I do!) but clearly this wasn't the case here - financial spam came way out on top of the list. What I did find interesting was that I didn't get a single 'Nigerian letter' offering me a share of $50,000,000, yet I often get several of these a day in my usual email account. So quite where these come from (and don't say 'Nigeria') I have no clue at all.
At last I was in a position to find out. The weeks of waiting, tossing and turning in bed, and counting spam emails instead of sheep was coming to an end. Eagerly I added up my columns of figures, desperate to reach a conclusion. Alright - it's not amazingly exciting, but I'm doing my best, ok? Actually, it was rather surprising.

By far and away the most spam came as a result of requesting not to receive anymore! This wasn’t actually that surprising, since I had a feeling that would be the case. However, the fact that a single posting to LIS-LINK resulted in 244 spam emails quite astonished me; almost 7 times the amount that I got from the pornographic site. (I should point out here that to be fair I discounted all the actual pornographic emails that I was sent, since I had in a way requested them – I just counted as spam anything that wasn’t pornography, ironically enough.) I was also surprised that my single posting to the Yahoo! group didn't result in any spam at all - perhaps I was just fortunate with the group that I chose.
I’m not going to pretend that my experiment was particularly scientific, but then it wasn’t really intended to be. However, I think it was rigorous enough to draw some interesting conclusions from it. Firstly, under no circumstances should you respond to a spam email and ask to be taken off a list. While you may get taken off that specific list it’s quite clear that you’re going to be added to plenty of others! Secondly, and perhaps rather worryingly, it does appear (from a spam standpoint) to be a very bad idea to post to mailing lists; certainly not those that have publically available archives. I don’t image that a spammer has actually bothered to join the list, but I think it’s more than possible that they send software to crawl through the archives and collect email addresses which are then added to their lists. Consequently, the more that you post, the more likely it is that you’re going to get spam – and quite a lot of it!
Well, that's a question that I can give a very quick and easy answer to; we're the losers. Anyone with an email address that is publically available on the Internet is almost certainly going to get spam at some point. Probably sooner rather than later I'm afraid to say. And the winners? Anyone who has managed to sell a septic tank across the Internet I should imagine!
