Title: 10,000th Member
Post by ThudanBlunder on Sep 19th, 2007, 4:39pm
The number of members has just passed 10000. In fact, the number of members has increased by 300 in the last couple of days! This ought to be a cause for celebration, yet something fishy is going on. There are almost 1000 members with names of the form newxxx@gmail.com, where x represents a digit and there are more that 500 members with names of the form nowxxx@gmail.com. In fact, now510@gmail.com was the 10000th member. What is more, none of these members ever post anything. And all of these 1500+ members seem to have joined in the last two weeks! Is a robot at work here?

Yea, I bet this is a bot!! We probably should include a authentic signature for signing up on the forum.. This would probably require immediate attention from William.

Yeah, these pseudo-members are probably wasting William's precious server resources.
Five new 'members' have joined in the last hour. But what is the point in it?

Adding authentic signature is a good move, but what do we do with these xxx-bots ?

Why do anything? They aren't causing any harm. Other than the server limit. But users cannot be deleted, so we must find the source any get it to stop.

bots like these are not easily dealt with except for making the server side code more robust!! Unless of course the person is dumb enough to run from the same machine!!

Who would do this and why?

Post by Sir Col on Sep 20th, 2007, 12:13am
The reason they do this is to obtain publicity for their product/website. What these bots are programmed to do is to register and add a signature with a link to the owner's website. As this forum is very popular it is regularly indexed by the major search engines and they trawl all of the links from the main page, including the members page. One security measure easily implemented is to not allow signatures to be added until the member has made, say, ten posts, and ensure it is removed from the registration form. A script could be easily crafted so that if the registrant submits a signature then it must be a bot trying to register and the registration process can be terminated.

However, these annoying bots are also programmed to make posts which contain links. This is much more difficult to guard against.

Hence the most effective method is getting a human response during registration. This is sometimes achieved by getting the user to perform some random calculation, answer some trivia question, but often done by getting the user to enter the code embeddd in an image, called CAPTCHA. Unfortunately most of the bot engines - and, yes, creating these is big business - at the moment have work arounds for the standard CAPTCHA systems. A customised system is the best way forward here.

None of these accounts seem to link to a website though. If they have a link in their signature, it doesn't show up anywhere without them posting.
The only thing they're doing is taking up a little bit of server space, but even that shouldn't be much.

I don't see people's signatures under member profiles. And I don't recall any settings under my profile that might make that different. Do you see them?

Post by srn347 on Sep 20th, 2007, 4:23pm
By authentic signature, do you mean one of those image things where they can't copy and paste it? By the way, if you can't see their sig, how do you know that it's a link?

I believe that he should add something to help protect the site from auto-registration. What I'm thinking is using what a lot of other sites do for registration, and that is having a picture with letters and numbers in it, and then having the person registering type in the characters. It won't hinder people who want to register, but it would stop spambots from registering.

Title: Re: 10,000th Member
Post by SMQ on Oct 9th, 2007, 10:25am
It's called a CAPTCHA (http://en.wikipedia.org/wiki/Captcha), and I guess there are software issues preventing one from being implemented here in the near future.  Longer term I'm sure some similar system will be instituted.

Post by towr on Oct 9th, 2007, 11:29am
Before the last update the forum did, for a while, have that. But it wasn't compatible with that upgrade.

Also, spam-software can now crack many of those CAPTCHA's, so they don't help all that much anymore.

Title: Re: 10,000th Member
Post by Aryabhatta on Oct 9th, 2007, 12:03pm
In the spirit of this site, perhaps we can just ask a simple puzzle before registration is allowed.

(Edit: I see that CAPTCHA covers asking puzzles etc. Sorry, I thought it was only about images)

One) they're also guests when they only look at the "only registered members can view this forum" page
Two) I don't think guest access is denied any more.

How do you access a guest pass? What does it comprise of? Is it only when looking at the forums and you are not logged in, does it apply you as a guest?

I just saw, and there are still about 400 nowXXX@gmail.com accounts. Scary.

I don't think the hacking of that board and the spam are related; other than in the sense that that board is dead and has no one looking after it to fix either problem.

Hey cool. The newest member (at least last time I checked) was not a "nowXXX@gmail.com" account.  :P

I doubt it's coming from one computer. And even if it were, there's a good chance the owner of the computer it's coming from doesn't know his computer is used for this.

Sorry for being so lazy  :-[

I wrote a script and 6,636 users which I think are probably fake were killed today. Attached is the deathlist.

Lately the bots have been getting really bad, so I will look into implementing some kind of CAPTCHA.

You could also consider using the lists and APIs from http://www.projecthoneypot.org/ or http://www.stopforumspam.com/ to identify likely bots and comment spammers.


We don't seem to get a lot of spam though, so it's not too bad in that sense. Maybe to weed out more fake registrations, you could send an activation-email to accounts with 0 posts and high-entropy names, then delete them after a week.

I can't remember. But in any case, spam bots have absolutely no problem reading and acting on verification emails. They expect them on registration.
If, however, you were to repeat it a month later, spam accounts are unlikely to respond (nor have they any motivation to, since they rarely use an account to spam for prolonged periods; they'd sooner register over and over). So you could use it to weed them out.
