That got patched, i think theres still a few that are up, but most of the people i know who had it in their profiles yahoo deleted them, this always happens, my friend was arguing with me after he got his up, i told him they would patch it again, this has happened like 3 or 4 times now. There are about 50 or so ids with actual custom colored profiles, i have one:
http://profiles.yahoo.com/hurricane
Theres a few nice ones, for the most part mainly plain colors. These were all made years back b4 yahoo banned them. Ne time new exploits pop up they eventually get wind of it and patch them. Heres a few:
http://profiles.yahoo.com/witchcraft
http://profiles.yahoo.com/-babygirl-
http://profiles.yahoo.com/eminem
http://profiles.yahoo.com/-freedom-
I will post a tutorial on how to do them here if a new exploit pops up.
