Anyways I was banned for posting on a locked thread. Prevent getting armatars that is not supposed to be got. Actually I don't know Graham's way, cause it was deleted before I could view it. But I myself have my own way. I think to prevent it, use javascript in picking Armatars. I know it will not clean out everything, it will prevent newbie hackers that know how to exploit html.
Prevent posting on locked threads I have no idea. I suppose you can add an "if" function, but I'm pretty sure the number of threads will make the site lag.
Prevent posting like a mod. Actually I think mods will ban that guy forever There is no need to actually infuse an anti hack for that one.
Anybody know how to prevent hacking high score table? You see, I hardly play games in AG, so I don't even bother exploiting the high score system. If anybody knows, feel free to share on how to stop it.
