When you lock a screenname, basicly you change the password. Changing the password makes the screenname unusable by the person who it belongs too. Obviously the person can just make a lost password request and have it sent to them, BUT, what many people (inluding myself until lately) do not know is that, you can use almost any characters in a screenname, up until recently you could use API calls to set the text to whatever you wanted, and using VB you could set text to characters that are not displayable, like the enter, tab, and delete key. Then, when someone trys to make a password request, they get a password like BLAMO and a carriage return, which is not displayable really. It looks like its not there. Since this has been fixed, the best way to fuck with someone is to use characters that are not displayed by Windows(vb can do it with Chr(15) etc) so that the characters just come up as blocks when they mame a password request, or you could set the password to blamo"undisplayable and it will appear in the email like this "blamo"undisplayable" so if there dumb, they might think there password is undisplayable or just try blamo. I would LMAO if they don't figure it out (thanks to Lint from ANTI-AOL.COM for the info)
