I found this very normal scenario to protect our community.
Im 100% people from here buying for fg at low price any given time in the league and then goes to another place and send items for real money.
This can destroy 5-10 players from here in a single day without beeing involved in real money tradings.
3-5 guys who does greedy moves here can kill poe section within days
Because of this reason after you get banned your trading list should be public or at least given to the mods/mediators for cleaning the house.
