That was my quick and easy solution to hiding the Seeking.com thread from appearing. That thread might not show in the thread listings for those who don't have SA access but it still showed on the frontpage when it got bumped.
Ahhh yes I see ... the two did coincide.
Off topic sections on specialist forums can be popular with some (myself included) but are notoriously problematic and confrontational (football, politics, religion especially) and the hassle of moderation, just isn't worth it ... especially if the moderation resides largely with one person on a very large forum.
It's a shame because they can be a useful source of help and information but the accompanying off topic discussion can drift well 'off topic' and become a extra battleground for rival factions.
I don't know the history of 'off topic' here, but suspect the membership was given one last chance within some updated criteria and didn't comply so patience ran out?
