Idea of bounty is welcomed in general but we should give them(Perp Team) to respond to all these allegation. And you can ask the team here
In total 1.3M token was converted to stable, 500K was for grant and builder which was paid in stable, not ideal but it depends on their agreement, if they agreed to pay in $OP or in Stable
They need to give clarification on rest (800K) $OP token, and as they have mentioned in their proposal that they will match the incentives 1:1, we also need to know if they dumped their native token as well or not ?
OP Team is aware of this and they are working on getting all the facts, lets just give them some time.
