You ran a bot on coinchat, probably with TF's help. You admitted this before, so you can't really deny it now:
I *did* use coinchat a few months ago and I was banned by "admin". We exchanged some emails in which I asked him what I had done to be banned and I didn't ever get a detailed response. He said I owed him 0.2BTC if I wanted to be reinstated on coinchat. I asked him several times where he came up with that number and what I had done wrong. Each time, however, he just replied tersely about some sort of fraud and paying him back.
The best guess I have at what he was angry about is that I was experimenting with robots on his site using the api the he published (and I as I understood it) he encouraged us to use. I enjoyed coinchat and I learned a lot about node.js while I was experimenting there.
Coinchat paid
people to chat, not bots. Bot owners on coinchat we're supposed to tag their bots with "bot" so that the system would mark them as inelligible for payments for the chatting they did.
So what exactly are you saying TF is lying about? are you saying your bots never received any payment for chatting? Or perhaps that TF said to you your bots were elligible to receive payments? This is what I don't understand at all. You claim the allegations are untrue, but don't say what is untrue, just that TF is a scammer, which is somewhat relevant of course but I have not took anything TF said into account here, only things you said and my knowledge of how coinchat worked.
You never said either of these things in the initial complaint or gave any other excuse so I suspect you did defraud coinchat, however this was a long time ago and the Bitcoin price was much lower too, approximately $128.50/BTC. So if you did defraud coinchat the amount you took was only ~$64. Not exactly the scam of the century, and as long as you don't have a history of doing this kind of thing then I don't think this on its own makes you very untrustworthy, nobody is perfect and everyone makes mistakes, there are no heros or villains in this world - only heroic and villainous acts.
Perhaps what you could do is offer to refund the $64 to someone who was scammed by TF. Maybe you could do this to "atone". However, the way you have acted when confronted about this by Quickseller doesn't exactly scream trustworthy at all.
