Beware of emails with these titles:
Compound Protocol Soft Fork User Walkthrough
Compound Cross-Chain Compatible Soft Fork Walkthrough

According to Etherscan, one of the scam contracts is still receiving txs up to this day. Hopefully these txs are all pending because the guy canceled his transaction (you can do that by submitting another tx with the same nonce but a higher gas fee)
