Spamming - Can I block IP Addresses?

[MarkDavid]

I am having such a problem with spammers and new users registering with the same IP address.

Is there a way that I can ban an IP address of a known spammer so that they may never register again??

And also, is there a way to set options so that the first post made by a new user must be approved by a moderator before it is displayed??

Thank you so much, I'm very new to this.

1) admincp--->settings--->options--->User Banning Options

2) Yes you can do it with Usergroup Promotions, the system will automatically promote users to a new usergroup once their first post has been approved. Just make a new usergroup for new users, set the promotion for one post and moderate all posts.
