I know, this is off topic but new guys asked, so here we go.
Icebraker? Icebraker is just a lonely idiot with too much free time on his hand. Ignore him and you do not regret it.
Asshole, who runs mpex, is called Mircea Popescu (yes, he named the exchange after himself, fkn narcissist indeed).
Mircea Popescu is a lunatic from Romania. He is too important (read: scared shitless) to use bitcointalk but you can see him ego-stroking himself in freenode irc. He loves to brag about beating up women (sound like he has serious mental issues and plethora of complexes involving his mother. Never mind that, for now.) He also gets off on telling everyone, how smart he actually is and how stupid the rest of the human race is. LOL.
This pompous scumbag from Romania has a sock puppet. You have probably met her. This seriously butt hurt sock puppet (no wonder it hurts, if Mirceas hand is up her ass all day long, to make her "lips move" - spam the bitcointalk) is called MPOE-PR :* She had a colourful career in porn site spamming (too lazy to look up the link).
His master Popescu is also a known spammer. His Polimedia.us used to be home for is one stock wunder-bazaar MPEX. Polimedia.us was also hosting a porn site. Some say, he was peddling kiddie porn too from that same address. Not surprised at all. He is seriously ill.
BTW, It is truly amazing, how 2 dipshits, MPOE-PR and Mircea Popescu actually met. Some say, hi is just hiding behind the skirt and writes all that crap himself. LOL, It makes him even more pathetic.
Cheers and welcome to bitcointalk - The bottomless cesspool of BTC world.
hahaah love it
