wiki - spambot?

Hi!

40 new wiki accounts and I guess that "Someone already noticed and did something about it" a while ago ("old news"). Got no idea if that's a spam-bot preparing for the big launch or something else I'm not familiar with either - just thought it worth mentioning in case everyone else thinks "Someone already noticed and did something about it" instead of doing something, too *g*.

( Something might be happening somewhere under some circumstances perhaps! Someone do somthing before something is to late! Oh, yes, and inform someone! OMG / RUUUUN/PANIC!!! )

Re: wiki - spambot?

Post back if they start spamming. I can't really block them as I might block accounts of innocent users in the process. But it does look suspicious as they seem to follow the same pattern.

Re: wiki - spambot?

Just look at the creation times. Bots or not, they definitely do not bode well. You could always check the IP and try to correlate it to a user on the forum. Otherwise it might be worth deleting all accounts created by that IP. Even if the wiki can be restored, if this in preparation for massive wiki vandalism, it will probably be a pain to fix later.

Re: wiki - spambot?

How DO you guys tell who/how many people have signed up for a wiki account?

From a total noob - is it possible to back up the wiki somehow?

Re: wiki - spambot?

I think it's starting to get a bit... "crowded"... can hardly see any real changes in the RSS feed between all those new "users".

So those accounts have no column in common, not even the encrypted password or something?

Re: wiki - spambot?

I have written a simple but working Plugin to stop spam bots. Maybe we could think about enabling it. I use it at archlinux.de and even without the need to be registered there is no spam.

Re: wiki - spambot?

Is there a way to see what IP they used to register? I can only see the time/date  of registration.

Re: wiki - spambot?

I'd say ban them before they can do anything. There are hundreds; IMO, it's too much of a risk to leave them.

EDIT: Roughly how big is the wiki? Could I just download the entire thing so there's a "backup" of sorts?

Re: wiki - spambot?

hmm sounds like a nice idea or have account creation either through request or with one of those security codes (random sequence of numbers and letters in an image) to prevent bots from registering

Re: wiki - spambot?

At least half of those accounts can't be real people.
I hate captcha, but this type of protection might work.

Uhh.. I'm positively sure I'd fail that big_smile
Also, with a limited number of choices, a bot has way better chances with this than with a traditional captha, methinks.

I've already taken this into account, abesto. 1/6 >> 1/20 ^ 3 (3 stages, 20 choices each, only one of the answers is correct).
No, I'm not going to implement it :-)

Re: wiki - spambot?

I saw that there was some discussion of adding captchas to the wiki on the arch.devel mailing list:

http://article.gmane.org/gmane.linux.arch.devel/6223

The assumption there seemed to be that it would be difficult to edit a wiki in a text browser.

http://article.gmane.org/gmane.linux.arch.devel/6230

In fact, it is quite easy and convenient to edit MediaWiki articles in emacs using emacs-w3m and wikipedia-mode.

I, for one, would put in a request not to implement a captcha, since it is an inconvenience for those who primarily use a text browser + text editor to contribute to wikis (rather than having to use a cumbersome graphical browser).
