There is some truth in that, and it often is a value judgement. However I do think bouncing a fifteen year old thread from a long-gone Palace fan celebrating making his 2000th post on NSC is beyond the pale.
I must admit it pisses me off as well, especially when the 'bounce' is only tangentially connected with the original topic. Poor Alex Salmond didn't even get his own RIP thread, it just got added to his court case one, which made for some interesting reading.
