This didn't happen recently, but it happened. I decided to give them a try and do my very first transfer into Crypto.scam was Ocean protocol. I received a warning when I started to send it stating, not working, only send ERC20 compatible tokens to said address. The Ocean Protocol I was sending was polygon and everyone who knows anything about crypto knows polygon is 100% ERC20 compatible. The thieving f@¢+$ locked up my tokens saying I sent the wrong tokens to the address and wanted me to pay 100USDT for them to retrieve my tokens. The tokens value was around $95. They better hope we never cross paths. They could improve by not stealing, scamming, and representing why some should of been swallowed instead of conceived. You can go to polygonscan and see my tokens using this address. 0x10fAEE08A0c354c3984002AadFAa8d3F8842B323
