I believe there are more users who were scammed, but let's see.
This should arise the question of the escrow jurisdiction.
If a project is to escrow $20k with any of the escrow agents or campaign managers in this forum or Altcoinstalks, that very escrow should be for both forums first before outsiders.
Seeing an escrow of $20k could be my motivation to swap $5k, but when scam happens, you'll be surprised to see someone outside the forum who was scammed even more than the escrow amount in this forum.
Regarding your concerns about escrow jurisdiction and the risk of large-scale scams, I believe that shifting from a passive "penalty fund" model to an active intermediary workflow provides significantly better protection for users.
By integrating the security deposit into the live workflow, I transform it from a passive promise into an active insurance policy. This allows me to act as a shield for the community, ensuring that even if a service attempts to fail, the impact on individual users is minimized or entirely mitigated before a total loss can occur.
