I put in an Anti-spam mod which obviously does not work for public forums, so I'll have to add something else tonight for that. Getting sick of deleting shit all the time.
Anyways, I forgot exactly how the new mod works, but I believe it requires a few seconds gap between loading the reply window, and hitting submit (bots just send immediately).
I did get one spam since installing the mod on the weekend, but that might've been human. We'll see how it goes.
