Yeah, something is going to have to be done by the admins. This is getting to be too much for the moderators to be able to--or even expected to--handle.
It's not getting better. It's getting worse.
Again, I think the real victims here are the moderators.
These forums have been through a lot. Running slow, gateway timeouts, it once said everyone had lost their account... Now daily attacks. There's got to be a real admin level solution.
