Based on my experience there, your chances of getting scammed is high and Paxful's moderators are easily fooled by experienced scammers. Even Paxful's CEO admitted that many disputes are basically decided on coin flips. (source:

If you still decide to sell gift cards there, consider not only your chances of getting scammed and but also being wronged by Paxful's mods.
To me Paxful is a great place for thieves to sell stolen gift cards or rip off naive gift card sellers, and the site manages to appear legit to some people because most scammers are ID verified, but even nearly fully verified Paxful accounts can be bought for $50-200 on legal sites. To what extent is this company willfully accommodating scammers? I think it's a matter of time before law enforcement catches up to how morally flexible this company really is. For now Paxful is still a small fish that can safely fly under uncle sam's radar.
