it appears that "the hooligans appear to be running wild on Joga.com. Please visit again soon; we will have order restored as soon as possible."

Google Accounts is being used to log in to this football community site.

Surely not suprise, just as the orkut communities. I assume the sport fans are more wild than the normal community memebers.
