is ARK slack sending out fake spam ethereum wallet (MEW) notifications to steal peoples' mnemonic phrases?
I think so, I'm getting the same thing. On mobile, if you long press to copy the link, you can see that it's not even the correct MEW site. It shows xn--myethrwallet-ivb
Not just a problem in the ARK slack... I'm getting multiple of these scam messages per day in different slack groups. The problem seems to be a weakness in Slack itself.
