I find it strange that a thread is deleted simply because it had been 'discussed to death'.. after all, is that not the intention of niche messageboards, and anyway, what harm does it do by remaining on strength? If no one wants to discuss it anymore, having had it been discussed to death, surely it just fades away anyway, as do the hundreds of others in the same situation?
Its not the role of moderators to completely stop a thread because some content may be repetitive (after all, what about the Chinook/Formula 1/Crickets threads elsewhere)? I take the point that a thread starter may have stopped one of the threads, but whatever you think about her actions, this is a subject relating to expression that does have ramifications and might affect how others are feeling/thinking of acting.
Respectfully,
