This forum does not ban scammers, there is no "court" here. And thanks to this, you can do anything and be sure that after a while everyone will forget everything and you can safely continue to work.
I am even sure that they hope that after some time, when I leave this forum, they will write to authoritative users and ask them to remove this feedback:
Negative trust can only be removed by the user who imposed it. And I highly doubt the DTs would grant reprieve to a scammer for any reason.
And you are right, this is not a court, just a community of crypto enthusiasts, and you are responsible for your own safety and security.
Regardless whether a user has aged trust or. OT, always trade with extreme caution.
