I’ve noticed that we seem to be getting a lot of spambots lately.
Is there anything that can be done about this?
I’ve changed the captcha to a question based one. Now they have to be able to do maths or read the Hitchhiker’s Guide to the Galaxy.
Much appreciated. 
Yay. Not really fond of the spambots. Thanks!
I think they might be exploiting a vulnerability in vBulletin. If so, there’s not much I can do to stop them.
