It's the Vance Miller kitchen spammers that seems to be the worst on my forums. Almost all come from Indionesian IP addresses including the hackers that have on one occasion caused my server to crash by using a program to brute force the admin & moderator account passwords.
Banning their IP addresses does not always work as they hide behind proxy servers. I ban the IP for 30 days because it will probably change later.
I have noticed that the spam on this forum has got worse recently indicating a spammer has got around the anti-spam systems. Often they will use a real human to figure out the Q&A and add it to a database for the spambot programs so this makes stopping them altogether impossible.
A Q&A based CAPTCHA using multiple questions and answers which gets changed often keeps spam to a minimum. Also forum software version must be kept up to date. Trick is to balance it to keep spammers at bay and not to put off genuine visitors who want to sign up by being forced to answer several stupid questions.
