Paxful shouldn't be on this list. I've been trading on Paxful for over a year now, without problems. Of course, I ran into people on the platform that are scammers a few times (just like on Localbitcoins), but the Paxful moderators have always resolved disputes fair and quickly, and were responsive when I reported scammers.
Regarding the references given, they all seem to be from people that didn't use 2FA. That makes your account very vulnerable for hacking.
Over 2,400 BTC is traded every week on Paxful. They don't deserve to be on a list of scammers.
