This issue has once been discussed between I and @scholaris about the issue of decentralization of this platform which he said this community does not have control over your asset
POB community, to my knowledge, doesn't have the authority to regulate how the token gets sold or bought in the manner you describe. Also, Hive allows people to have multiple accounts. If I restrict someone from selling POB until they meet criteria why can't I do that for any other token or Hive? You can't force people to stake their coin. You can only encourage it. It's their money.

So this question of yours is also a question in my heart to centralize this decentralized platform to gain full controls and take a great precaution and act to anything illegal in this community.
