Set up more accounts if you want.
I can eliminate brute force, my password is 6 characters alphanumeric and non dictionary. It also takes 1 second per request to login via FTP etc etc so I don't think it's pheasable.
I saw a guest on my site (I track guests) and he had 11,000 page views in a day, so hes suspect. However, his IP address was the same IP as my server? What's going on there?
I want to put a limit on messages per day, but how? If I put it on accounts, he can set new accounts up. He also is probably spoofing his IP address so I can't do it on that.
