Yes I do remember it and I did leave negative feedback for the user for several over-the-top posts. He wrote to me later asking me to remove the negative trust because he said he was genuinely duped by the Minexcoin and Republia scammers. Truth is, many people were duped by the Minexcoin scam. Since that time he has made a couple anti-Minexcoin and anti-Republia posts too including these:

Minexcoin: https://bitcointalk.org/index.php?topic=5090539.msg52742818#msg52742818
Republia: https://bitcointalk.org/index.php?topic=4841968.msg51829104#msg51829104

Everybody can make a mistake. Scammers such as Boris and his inner circle scammer alliance consisting of Temhuk and pool operator Racquemis1 along with paid trolls such as Jedgar, Yurii Pohrebniak / yurez83, akira128 were in full flow using this forum as a platform lying and scheming trying to fool as many people as possible in to believing this trash-coin project so lots of users were duped. I remember when some users they received their "pre-paid cards" in the post their support for Minexcoin went in to overdrive. Inevitably it all collapsed and the scam unfolded.

I removed my red trust for the user you mentioned rather than revise it to neutral because he said he lost 2 BTC in the MNX scam and was genuinely sorry for backing this scam in the first place. Some of us knew from day one this was a massive scam but others found out later.
