Thanks Buddy!! Sure I ll get back to you if I still face some trouble with spam posts.I have a vbulletin forum if you need help message me I will show you what to do. how to stop all my spam has stopped.
Don't waste your time with banning IPs and stupid junk like that. It won't solve anything. Most of us xrumers users have VPNs, proxies, etc. If you ban our IP, I'll have a new IP again soon. Just make a custom security question about your topic that xrumer cannot answer. If you do dog training, make it a dog question. You can also disable signatures until the users reach 5-10 posts.
Problem solved!
Moderating each new user is an option for a small forum, however I get hundreds of new users each day across all my sites so I had to come up with something more realistic.
First use akismet and Most of the spam will be trapped for moderation.
Um isn't Akismet for WordPress only? OP's forum is getting spammed.
