I run an OTC peer to peer exchange on telegram. There are verified trusted sellers that people buy from to avoid getting scammed. And this is one of the vectors that scammers use. On telegram, it's easy to clone a person and DM people to trade with them. The victim not aware, sends coins to the scammer and therefore loses their money.
I thought about a way to fix this by linking verified usernames to links with their addresses that can't be changed. Though, this is just a rough thought, that's how the idea for coinprofile came.
