BOT LIST?

[I.G.O.T.A.]

I have 4 forums, and one is constantly getting hammered by fake users (bots). They get blocked and denied, but is there anyway to get off their list. My other 3 forums get just a few a day, but one gets about 150 that never get in, but they never stop.

Also someone is constantly trying to log into my users accounts on that forum.

Any ideas on how I can stop this?
