Logging out helps if you suspect someone is inside your account, because that way you logged him/her/that out too.
So if you were CGed then logging out then back in won't help huh? As they have the hash of your password?
(I've personally proven this by entering on different browsers to an account, and logging out in one logged me out on everyone)
But it's not enough if they already have your info (hat's why one must also change password).
I joined this site instead of other neopets cheat sites because I liked the way the admins think and how they worked
I told him we don't support that, and told him a way how he can use his knowledge for good.
