Im sorry this is happening here also Chris..
For the longest time they werent hitting my friend SKIPs site (
www.hipforums.com/forum) but a few weeks they started on him also.. (I thought we were lucky there and they didnt know of his site)
He also blocks guest access if the traffic is high...
These stupid AI bots are causing problems for everyone and its disgusting!!
