I have also been getting a lot of registrations from the cashette and mail.ru addresses. Setting new registrations to confirm email addresses seems to have stopped them posting so I'm guessing they are fake addresses. I just banned those addresses to cut down the amount of accounts I have to keep deleting.
I think this is being done so that they can then post a spammy posts with links to their sites as I found a username 'buy-prozac-online' on another forum and it was just a keyword loaded spam post.
My question is, do you think these accounts being auto generated, and if so, why isn't the image verification putting a stop to this? Have people found a way to get round it?
