So I'm having the same issue as another user, im unable to post comments due to a message saying 'awaiting moderator approval'. I've checked and month-old comments still haven't been posted. None of my comments go against the ToS in any way, and I've contacted support but received no response :/. Here's the message:
Awaiting moderator approval
