My friend recommended me this exchange to trade but I wanted to KYC in advance to avoid any surprises. It may be strict, but I passed it, just followed the instructions and got verified in a couple of days. No complaints of any edited photos from them, the procedure is clear and straightforward. So far so good, hope it stays that way

You have not faced any issues as you have provided all the perfect documents and you have no alternative accounts on there. But if you had multiple accounts and you could not provide real document and tried to provide fake document then you could understand about those who faces issues and issues.
Why would you provide fake document tho? For what reason? I guess this is the root of the problem, but honestly, nothing surprising. They say "fool me once..." you get it. Also as i can see, they provide subaccounts (same KYC, different email), why create many?
