anyone know what s happened to famed hackforums.net.In recent days, i could not access it and received 403 forbidden page. Is it in trouble with police like megaupload??sorry for my bad question, but i do not know where to ask

Well, this place is about Reverse Engineering NOT Hacking (it's not the same you know?!)
But to answer your question: these "hackforums" are perfectly accessible for me, without any delay. I can only imagine, that they are blocking US ip's. As long as you are not from the US or using a proxy, this shouldn't affect you.

Also works for me.. :P

and one of most useless sites (forums) ever..

I agree it is useless, I'm a total newbie here but I post about debugging over on HF and I'm like a god.
