Please ban user: lovevps1 -He giving FAKE REVIEW to me
Negative trust is not moderated. Users are not banned for leaving (possibly fake) reviews.
I haven't any exchange with him...He said I scammed him 0,1 BTC ...
Like Shorena said, the trust page isn't moderated... I know it's not fun having a negative remark on there, but i'm afraid there's not much you can do...
If i were you, i'd PM lovevps1 and kindly ask him what went wrong... explain the fact that you don't recall doing any business with him, and ask if he/she can show you the tx-id's from the transaction he/she did with you...
If he doesn't answer, and it's important enough for you, you can make a thread in the reputation section, but chances of getting the neg revoked are slim if you chose this option.
All in all, red trust from an untrusted member isn't the end of the world, but i understand it's not fun.
