Sure. But we’re a group of volunteers and we would not like to find out the hard way what is possible and what not. We would think meta discussions about piracy should be allowed as long as there is no linking to actual illegal content.
But is pointing to locations with illegal content legal or not? And having members/admins worldwide it makes it even harder to be sure.
We don’t want to find out the hard way and this is a better safe than sorry measure. Again we personally have nothing against the people on these communities or against the communities itself.
