I gave him a negative feedback because he put my name in the distrust list for no reason and he did the same with my second account Virtualis Games for no reason.
You're going at this the wrong way. Please start by reading
LoyceV's Beginners guide to correct use of the Trust system (translated into 12 different languages, which shows broad community support for what I wrote).
First: anyone can include or exclude anyone they want. This isn't moderated, but more importantly: you shouldn't take it personally!
Anyone can also leave anyone any feedback they want. This too isn't moderated. However, if you ever want your feedback to mean something (by reaching DefaulTrust), you'll need others to include you, which they may do if they think you leave valid feedback.
He put my name in the distrust list because i was trying to explain myself about a situation where TECshare made an error but TECshare was trying to make me close my mouth like a dishonest person.
Again: you're taking the wrong approach. You could discuss this in a new Reputation thread, but none of this is a reason to leave negative feedback.
He put "ABitNut" in the trust list
TECSHARE included ABitNut
more than a year ago. The only thing that changed is that
TECSHARE reached DT1 recently.
but this user abused of the feedback system since he gave me a negative feedback for "multi account" without any reason (muti account and what ? it makes me a scammer ?)
I don't know. If you open a new topic for this, I'm willing to look into the evidence. But it still doesn't justify negative feedback.
