New Forum Spam is killing it
 

I am trying to develop a new forum. Within the week or so that it has been up I had over 200 users who are just spamming me to death. I just set all the forums to require a moderator for psoting but wondering this:

How do I prevent spammers from being a user on my site?

How do I delete all there old post?

How do I moderate the froums? is there a way to do it without having a moderator having to go through all the post?

Where is the best place to learn how to run vbullein cause I feel like I am way over my head.

Help a greenhorn out!
