i made an alt once to tease some guy that was randomly telling his friend in a topic about his name change. i got on as (whatever his name was) and made some smartass reply. 1 post and i forgot the pass lol.
im sure my IP shows that im all of: Bisjac, Cookie, Lippy, Rughugger, whatever my brother's account was.
and that half of them are all used on like 4 diff IPs, and of the same.
who knows
