I think that there should be RULE again extortions and ban them for ever.
In any other paltform this is form of threats are not acceptable.

You can never say things like this in Airbnb or Localbitcoins. PAXFUL , or other other platform that respect itself.

For example when Yahoo tried to extort me to stop harrass him or he will give me evil fee to pay. (this kind of extrotntion/blackmail)

Here proof


Also I see malcious and dangers users who extort people in the past like owlcatz

He is very dangerous to the community and can put all the community  in which harm and shock.
