.. careful with this one. I got a Telegram request from "John Smith" @Smith123 trying to convince me to deal with escrow providers whose email generate Gmail verification warnings.
He claims the Gmail warnings are due to the PGP block and to just ignore the warning and deposit BTC anyway and if I don't do so immediately it's because I'm a scammer
He threatened to sic the SWAT team on me if I didn't send BTC right now. 
He can send you email from Tomatocage or Monbux that look convincing enough (except for the Gmail verification warnings).
