Poloniex has been citing "growth outgrowing their support staff" as an excuse for pathetically horrible support response time for most of the past YEAR now.
This is ONE of the reasons I stopped using them.
They also dropped their "chat box" which seemed like the only way to ever get a support ticket paid attention to....
Once they dropped their chat box I moved most of my funds off of their exchange as well. While it was annoying at times, I figured the troll box would provide the first clues of any big issues in case I needed to act quickly. Now with no immediate feedback mechanism to warn of impending danger, it could very well turn into a Cryptsy type situation.
I know I should move all my coins off, but they do have a couple of unique markets I still like to trade in. It is a very small amount so if they do go under, while it may piss me off, it won't really be a significant loss.
