Guests problem. +500 guests all with different IPs and no refering address

[GameArtisan]

On Sunday, my forum's guests count went from 60-80 average to +500. When I check the stats of who is online, all these mysterious guests are viewing 3 specific profiles, which are actually spam profiles. These 3 profiles were created by the following IP address: 89.0.188.155. I have banned this ip address from accessing my entire site. However, the guest abusive problem persists.

Has anyone had this problem before? And how do I stop it?

:confused:

put 'track visit guest' hack made by PM and check who are and what they do over your board ... it's easy that many of these are simply spiders ...
