Over the last few months, I have had many spambots register for my site which always post messages advertising either cialis or viagra. I have complicated security codes enabled but it doesn't seem to be stopping many of them. I am unsure of other methods to employ to weed out these spambots without inconveniencing real new users of my site.
Looking at the profiles of the spambots, I noticed that every single one of them registered with an email address within the domain yandex.com (e.g. the email addresses are email@example.com, firstname.lastname@example.org, etc.), which appears to be a popular Russian domain.
Is it possible to block users from registering based on the fact that they have an email at this domain? My users (current and potential) are almost entirely in the US and Canada, so I am not worried about the possibility of a real user trying to register under the yandex.com domain.

D_F, There is no such feature on standard uCoz system. May i know which module, the spam bots are posting messages on, is it the comments section on site news or on the forums?
You can "Block activity of users with unconfirmed e-mails", in Module settings in Users section.

Xayaan, thank you for your reply and suggestion. I suspected that there was no such feature.
Regarding where the spambots are posting, I should have specified - it's on the forum section. My site is http://theexodus.ucoz.com . Thanks!

D_F, you can try to change the complexity of the security code in Control Panel > Settings > Common settings > Type of security code (captcha).
I'm not active on the forum anymore. Please contact other forum staff.

I currently have complicated captcha enabled - do you think changing that to one of the "weaker" settings would actually help?

D_F, if the spammers are not humans, it could help, but it's not completely sure. uCoz has a strong CAPTCHA, which can be hardly fooled.

Thanks for your reply. However, I definitely think the spammers are robots and they are obviously fooling the complicated captcha.
My forum is divided into two sub-forums, with one being devoted to actual discussions and the other being the area where I post FAQ, "how to", etc. So if the spammers had half a brain they would at least post in the forum where the actual discussions are. But instead they have always, without exception posted in the "site help" area.
