I had no issues with my account, but when I heard the reports about accounts getting closed I got worried. And when I saw that this Bittrex guy on Twitter behaved like a dick, I moved my coins outta there as quickly as possible.

Just a wild guess, but if the affected accounts all belong to middle east-ish countries, it could mean this is some sort of measere against terrorism and how they finance their operations.

In any case, an xchange with bad communication and bad rumors is a red flad for me.
