email and cellphone number constantly?
Who is still using Paxful mate? I believe it was due to some scam activities that took place there years back that's why security measures is really taking serious. I will want you to make a move we have binance we have luno we have crypto.com and so many new Exchange where you can buy and sell.
I think you didn't know what Paxful is, its a p2p exchange similar to LBC but the problem with OP is that he doesn't what to submit KYC and he wants to sell. And he circumvent LBC's TOS by creating multi-account with is obviously against the rule and when you're caught, chances are you are going to lose your precious BTC.
I think the only way is for the OP to submit his documents, or move away from the platform. And look for other options like what others have posted already.
