I'm so sorry to hear of your woes... whereas this kind of stuff is generally not PayPal's fault, the service is used extensively to run a variety of scams... especially through craigslist.

If I were you. I'd escalate with PayPal by calling their fraud department and going step by step. Usually you get a whole different kind of treatment when you upgrade a "problem" to "fraud," at least that has been my experience.

I've never used LTBC-- always seemed to high risk and open to scammy possibilities-- but you seem to have had success with it. My typical cashout route is Steemit ►Bittrex ► Coinbase ► PayPal... usually goes from Steem/SBD to USD in my PayPal account in less than 2 hours... never had an issue (touching wood).
