It seems that fox.exchange is doing the same thing recently, except that they dont need for users to register but they will (most likely) randomly ask for people to send documents in the name of KYC/AML compliance but they seem to be doing it to scam people. You can see a lot of people are giving bad reviews(Trustpilot, Bestchange, forums,...) for this kind of issue.
You can check my post about this (
https://bitcointalk.org/index.php?topic=5318850). Just go to the links i've listed and you'll see that recently a lot of people are having these issues. They were the ones that got the less fees in the Bestchange list recently, i think the FOMO by people trying to get in and buy different crypto and try to make money doing that has led them to make such scammy tactics cause of course most people wont send documents to a non-registered exchanger and will likely leave the coins and move on with a loss.
I hope im wrong though as i am still waiting for a refund.
Im wondering on how you do people ending up on using those unknown or unpopular exchangers out there?
You got it right that somewhat FOMO did really make out some influence on making out such decision on where people do rushing up on buying crypto without even bothering
on where they do end up on until they do realize that they are already engaged on a shady or scammy exchange.
This doesnt exclude even into those reputable exchangers where issues like this about selective scamming is a bit obvious.
