He can blacklist servers.That's cool, but what you got on your blacklist? I don't make any kind of script that will block blacklisted people pay/donate to your ots, all I want is collect them more and more so we warn eachother and prevent loosing our money.
Well, allowing anyone to add peope lto the list will be VERY missused.
