I am a moderator on a small zelda fansite known as wiizelda.net, and we are having a rather large problem. There has been a person spamming our forums and creating new account whenever we ban them. He just changes his ip whenever we ban it. The forums use xenforo. Does anybody have any ideas for a permanent solution, or are we just going to keep waiting for the owner to wake up during his strange timezone and delete a bunch of spam threads every night.
