It's part of the changing face of cann.com CC, the owner of the site wants to promote a positive image of us to the world to help in the campaign towards the legalisation of medicinal cannabis. But it seems to be back now, for how long don't ask me. I'm not personally too bothered about those type of threads I rarely post in them, I don't see the harm in them either. That is why I believe it got taken down, same reason as many threads have been disappearing recently.
