Befriended on instagram over 5 months. Finally coerced to transfer USDT into the above 2 platforms through a coinbase wallet. Was told to receive a voucher which turned out to be a malicious smart contract allowing scammer complete access to victim's wallet. It turns out that coinbase wallet doesn't have the added security of 2 factor authentication which comes on when transfers were occurring. Also, coinbase wallet cannot be connected via Web3 (unlike metamask or wallet connect) to revoke token approvals

Smart contract connection with Coinbase allows scammers to withdraw as much as they want without explicit permission from users
