It's not the only one that was taken down. Some of them have just been tagged as "deleted". Others, perhaps those with more traction, have been disappeared completely.

The 'justification' theyre using is, "We run this forum to manage feature requests". The implication being that a stable, secure, trustworthy product is not a feature we can request.
