Actually the hack was done last night. I was in their IRC server when it happened. They fixed it really fast and pretended like nothing happened :P. It wasn't that big a deal. I saved the defaced page to my hd, but since zone-h got it I guess that wasn't necessary. I would never have known it was defaced because I never go to forum index page. I surf through the main page which wasn't affected, and the main page links to specific threads which also weren't affected. So summing up. Yes, they were "hacked", but it was minor and I think all is good now.
