you mean social threads with ***-for-tat replies ?
While I agree that its annoying when someone bumbs a thread up with a one-liner just for spite, there is not anything worthwile to 'clog'. All I see are about a DOZEN of social threads with posters bantering on school, games, and all teen-related extras.
Threads die anyway so whats there to clog ? The social threads live on so what is there to clog ?
