I see already some context via Google search, but didn't find it here. So just to make sure everyone is aware.

Scammers use NFT's, make YouTube comments, Reddit or any other means possible to show their Wallet Private Key (!), usually containing a couple of thousands USDT (Tron) on it.

Unaware Folks will go to those wallets thinking they get some easy money, but obviously they can't send the USDT to their wallet because there is insufficient TRX to complete the Transaction.

The scammers wait until TRX are loaded onto the Wallet, the "unaware folks" i refered to so far is also scammers actually, who wanted to grab some easy money.

Oviously the owners of the Wallet containing the USDT Wallet are using a Multi-Sig Wallet, once the TRX are loaded they are gone and transfer into their hidden Main wallet. Even if they would not do this and the person trying to grab the easy money manages to forward to his personal address the transfer will not go trough as there wont be any permission to do so again due to the MultiSig Wallet needing at least 1 , probably 2 approvals from the Wallet owner.

So the person who thought he/she can grab some easy Money gets scammed for the TRX send. The Scammers keep going with this to get more TRX. The Scammers get scammed by the Scammers

Personally i went to one of the Wallets and observed, they didnt get any of my TRX and i never intended to steal (Beleive it or not)
