Apple blocked it because of the myriad "ass threads" in the forums. The offending threads were closed, which means the app goes back in the pending approval line, so if they're going to approve it it'll still be another week or 2 before you hear anything about it. Honestly, though, there are so many threads here worse than those ass threads, so if Apple is going to continue being as draconian as ever with their app guidelines it might never come back.
