To make a restricted screenname you need to register an AOL Account with Foreign Certificate (Argentina is the most popular) you can make names with things like, SHIT, ASS, CUNT, etc. Then sign-on AIM with it, so when your account dies, you can still use it.
Another way to do it, is to create an AIM Screenname, using these words:
fucci
cocke
babcock
drape
krape
rapen
jrape
Like i have the screenname 'RAPEN YOUR MOM' and 'RAPEN YOUR ASS' Rapen is valid, you can make screennames with this in it, then format them to your desire, like 'RAPENAOMI' could be 'RAPE NAOMI'
I want to thank the people that have sent me these should-be restricted names...aspecialy shkbobo
