PM/Chat Logs: He deleted all
Of course he removed our talks on TG but I am sure have enough info to prove my words
Not this again 
How many more times are people going to fall for this? Telegram is a paradise for scammers, as it allows to remove all evidence from the other party. Use Bitcointalk PM for trade deals, or a public topic, or even CC LoyceVs PM publisher for evidence. You can use any messenger you want, but at least make sure the details of the trade including payment addresses are recorded somewhere.
None of this helps you now, but it makes things so much easier in the future.
That being said: now there's a bunch of screenshots and a bunch of accusations in both directions. It's really difficult to know for sure what's true now. My gut feeling gives me a pretty good idea, but I don't like the lack of hard evidence in cases like this.
As I said, my only proof is the thousands of articles I have created for this person!
This sounds like something you should be able to prove. Can you share 2000 of your articles?
