What about for new users they have to have their first 10 or so posts approved?
Either that or more mods I guess to cut down on the time they spend on here

What about, as someone else said, each new user needs to be approved, and then the first 10 post's, and banning of any accounts that do pop up. Also a on site firewall should keep em back

They all sound like too much work for the moderators my solution is kind of better because you can make your own questions using that mod, it'll take the bots a month to break through if their programmer discovers the answer to the question/questions.

What if they hack the forum? Like eliminate every information, O.O
And what if those bots hack accounts? OMG
