According to statement added to Joga.com site

(when clicking big EVENTS picture at main site www.joga.com)

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."

When researching the case Google's cache has similar information as early as 27th Jun 2006.
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.
