It is difficult to know where to draw the line, as Joe Offer says what do we do? I would be tempted to delete all negative non folk-related threads like this one, but I'm sure certain people would be up in arms if that happened.
Moderating any site is a difficult set of 'will I?', 'won't I?' decisions, and we have all seen threads deleted and then re-instated, which unless it was deleted accidentally is hard to understand sometimes. It's a bit like digging a murdered body up, just so's we can shot it dead all over again.
We do keep picking at this particular scab and making it bleed again, and I suspect we always will.
Go pick your guitars and your banjos, and leave the Cat to heal.
