Beware: Scam with @steemmexc address on MEXC, 3607 STEEM lost

I became a victim of scam: I sent 3607.002 STEEM to @steemmexc (TxID: 62b65ab5427c765547ce6001237263c2f7979b18) expecting 1.5% bonus. The first transaction (251.5 STEEM) came back with the bonus, the second did not. After posting on X received suspicious messages from @Dave_Hawkshaw
with "help". Do not send tokens to this address! Who has encountered this?
