It's likely one of two thing. Forum Mods nailing the post with the delete hammer because said thread made one teeny tiny comment that was negative about ZoS. Or because there's 99999999 threads about how the sky is falling due to ZoS's B2P+P2P announcement today literally pushed threads pages deep in a matter of a few hours.
Possibly on page 2-4 of the General Discussion forum? Threads are being made so fast that the ones made earlier are being shuffled down the recency list?
