This is probably of interest to no one but me, but here’s the current list of IP Addresses that I’ve banned from the site because of repeated spam attacks. I imagine a few of them are fake addresses, but here they are.

I haven’t tried to contact all of the hosts, but none of the hosts I have tried to contact about their domains being used for spamming have as much as written back acknowledging the problem.

On the other hand, I’ve had fewer difficulties with repeated attacks since I started aggressively IP banning. There are still a few who move their address around repeatedly, but this seems to have caught the worst of them.
