Help needed please...

[tribaleditor]

Hi there, I am running vbadvancedl v2.2.1 and I have a massive spammer problem.
I think I need to do 2 things, firstly I need to find a way of keeping the spammers out, and secondly I need to send all members a PM which they have to reply to to keep there account.
Can some one point me in the right direction please. My site is a free site and I don't make money from it, so if some one could help me rather then charge me it would be most appreciated.
Thanks for your time. T

There are probably other options around too.
