When the bounty is over, the team is making new plans so that they can easily escape by cheating.
This is always be the case,
They find so many reasons to delay the distribution of the bounty until they finally be able to escape from paying the bounty hunters. I have experieced a lot with this kind of exit scam, they pretended to keep on updating on their telegram channel and keep on updating about the exchange until they disappear after a few days or weeks.
