Can we get more rules on party finder

[ItMe]

what's funny about this is that Asmongold was a run seller in WoW (an aboveboard, gold-only run seller, note) and has said as much in his videos

Wait, what?
I only loosely follow what happens with WoW news, so forgive me if I'm late to the party but... is this real?
I thought Asmongold was supposed to be a pretty respectable player.

Also, you say they were an "aboveboard" run seller.
Can you unpack that for me? Like, did ActiBlizz know about them? Or was it just an open secret in the community?
