Part of my daily ritual now is going through the forum registrations. Usually a dozen or so now but was over 30 at one stage. I then add the ip address or address range to the block list. Russia, Ukraine and China are particularly blocked.
95% of the traffic to this site is forbidden currently.

As Bob just found out, you may find one day that you get a 403 forbidden error. If you do send me an email with your IP address and I will unblock you.
