What happened: Coinxback SCAM is sending messages in discord and asking people to pay them, and they also have fake SCAM google extension
The site has been flagged by MetaMask, I am getting the error message "Ethereum Phishing Detection" it is likely that this extension is dangerous.
It is still appears in chrome web store so I hope everyone to report again.
