I don't understand this exactly but you don't have to prove they are legit and neither do they. They don't need anyone vouching for them either.
Constantly amazed at this stuff. If those that allege have some 'real' evidence send in a ticket. Why don't you just tie a rock to a clown (whoever they may be) and throw them into a lake. If they float they are evil; if they drown they are innocent. That's the system of justice dispensed here.
I prefer the innocent unless proven guilty approach so just report them.
Or perhaps I should say, if you cant provide the report here, then you have no evidence and are only throwing mud hoping some of it sticks.
Enough of this now please. It started from nothing at all and it hasn't improved.
