TFT Blacklist me please help.

Sorry, tft is not affiliated with GGG .
Crying on this forum does nothing.
You can do another discord account and continue using TFT ( probably).
No one cares if you delete the game, because you got wrongly banned.
If you spent money on the game you should probably have some trade tabs to sell your things and you can use 820 to provide services probably.

The only thing TFT does good is what GGG doesn't want to do. Facilitate bulk trading in 3-5 clicks and provide a platform for services like carries/achievement selling .

Since GGG doesn't want to implement a "service" trade tab ( because yea, they cannot guarantee the trade in any way), TFT will keep on going.
