Yeah, this wouldn't be at all unique to Paxful.
I don't think this is really tag-worthy behaviour anymore (Polo/Bittrex and a whole bunch of other exchanges were sort-of let off scott-free after doing similar stuff.) - although I really do think it should be.
I haven't followed paxful for a while, but if they did retroactively block old customers' funds without giving them a chance, well really, even if they gave several warnings beforehand... - that's indeed scummy, and entirely in line with their site's policy and userbase.
The amount of trust-circles which pad one's reputation might just make up 90% of their total trades, at least it did when i briefly used them.
The funny thing is: Only legit people are really affected by this; It would be trivial to photoshop a document / selfie to pass KYC, heck, you can buy a set for < 100$.
Especially for a lot of unbanked/underdeveloped countries (the unbanking they claim to support: (E: large portions of African/South American/South-East Asian countries)), it is actually impossible to verify their ID's beyond checking for photoshop. (There'd be simply no way to verify these ID's with something like equifax, although i sincerely question whether paxful even has access to something like that for her U.S customers.)
So it's either just window-dressing, or actual nefarious behaviour. (Although a strong case for the latter could be made regardless.)
Anyway, long story short, these P2P exchanges suck and are full of scammers.
After all, there was an entry here that KYC makes no sense at all and even helps criminals to act at the expense of innocent victims. This is all one big absurdity!
