It is difficult.
Everyone knows how generous MNers can be (as I said on the last deleted thread I (well, my child's school) have benefitted enormously from sponsorship for a fun run to raise funds for essential equipment - that equipment has changed the lives of the pupils involved, literally. but it was an awful lot of money, and I was truly humbled that strangers (essentially - I was a little better known under my previous name, but not 'famous') could give so much, and on faith (and a posting history)), and so inevitably there will be times where people post with that in mind.
who is to say hwo it shoudl be managed? MNHQ cannot get involved - I thik a poster said on the previous thread (or the one before 
) that this would mean setting up as a charity, and there are massive implications with that. and besides, how would it be managed? everyone has a cause that 'deserves' funding, or is in need themselves - who is to say one is more worthy than the other?
it might be an idea to ban paypal addresses, I suppose - instant deletion. but there is always PM to get around that.
I don't think deletion of whole threads is the answer, though - it only leads to specualtion and further threads (and I don't like the new policy of being able to get a thread deleted because it isn't ging the way you thought it would).
FWIW, I don't htink there was any troll hunting in the more cautious posts last night.
