Yes we know who does it and it was a group from Brazil, not connected to ofpec. And it's about equivalent to going out and smashing up a buss-booth or shop-window. It's useless, no one thinks you are cool and you just show your lack of social competence.
Now. mind you i've tried to tighten up the secrets abit on this system especially in regard to php. So if things are broken on ofpec due to this, please just report it and we'll try to fix it as soon as we get to it.
