I tried logging on to my account a week ago only to find out my IP had been blocked by Poloniex... Luckily I had a VPN available which I used to immediately log on and liquidate my portfolio (at a minor loss) and migrate to Bittrex.

I've never used the trollbox and only trade in small amounts on that exchange, so I have no idea what spurred my shadow-ban.

Either way, sketchy stuff going down on Poloniex. BUYERS BEWARE.
