I found this out the hard way.
Anyway..
After you've hacked or scammed someone that has annoyed you or whatever and you just want to make them cry.
Details.
How to do it:
What you do is you delete there character or whatever send all there gold to your account what ever.
Then go to character creation.
And just spam click the 'Randomize name' and spamm enter.
What does this do?
This will create alot of characters over the 10 character limit.
Making them not be able to login.
It will say 'Error loading character list' or something onlong those lines.
Funny Part.
After they go seek GM help to delete all there characters that are unwanted.
He will find that his characters have be owned.
So he's gone through all this effort to get his account back to find his chars have been pwned.
'I found this out the hard way.'
I couldn't find a character name some I thought I'd just randomize it. I went through about 30 names none where there so I spammed it and when I pressed ESC. I got this error.
Note: You make need to go through a few names to find a name that hasn't been taken.
I decided to put this in exploits because it kinda is.
