Absolutely going to go nowhere near the knitting circle politics of this "situation", but the disappearing of all trust previously left by an ousted member of Default Trust seems to be pretty daft.
Presumably they were trustworthy and valued at some point in time, before the wind changed?
Surely, as "Nights of the Cross Thru's" like this are relatively rare, previously left positives and negatives should stand, unless challenged and then arbitrated on.
