Temp Ban for False Pins?

If it's the real owner, then they can't log in for five minutes with the IP or account block.
If it's not the real owner, the account block would stop the real owner. A bot would keep the account 'banned' all day. ._.

Y'know how easy it is to bypass an ip ban?

I won't say specifically how, but think for a moment how much people have bypassed and made mults on forums.

I'm sure others could think of more complicated ip bans, but it's a really complicated matter. Personally I think it'd be easier by making it so that to unlock the ban, all you'd have to do is answer a question and type in another pin/password. I'm guessing they're planning on using Secret question #1 (?) for this purpose.
