In short you left a negative feedback on Ratimov profile because he commit plagiarism and aggressive? that's not correct. Despite Ratimov did such thing, I believe many users still trust him since he earn 10K+ merits and joining in a top campaign.
Trust isn't about the opinion, but I refer to trade/exchange where trust feedback is used to. But, do you think I will say Ratimov was right to leave negative feedback in your profile? nope.
It's right for you to distrust him, not leaving negative feedback.
Two wrongs don't make a right, it's simple to clear up this case, both of you need to withdraw the negative feedback and click ignore if you don't want to read his post[/url]
