Hm, hm. Yahoo's rudimentary security 'features' such as account
lockout policy (12 hours after several failed login attempts) is most
often used as a DoS against that account owner.
Plus numerous "booters" exploiting holes (read: buffer overflows) in
ypager.exe, and you have a perfect way to kick someone out from chat
and not let him/her/it return.
They (at Yahoo) try to make it harder to write your own chat
client/bot/messanger by slightly changing their CRAM (and still, it
was reversed, nevermind that it nowadays consist of several MD5-like
routines and is heavily obfuscated against casual reverse-engineers
:P)

Couldn't hold myself, this is FD after all :)
