I am seriously, seriously not trying to facilitate panic, but it would seem to me that the word should get out there, on a large scale, that this exchange is acting in a way that should worry people. This doesn't just impact the customers of the exchange, but the entire crypto market. Some people are very worried about this, and it would seem that they have very good reason. Poloniex's behavior is reminiscent of a few other large companies which have vaporized recently.
It's common knowledge around Steemit at this point I think. The problem is - what can anybody do?
Polo is also stating not existing problems with BTS. Look at this https://bitsharestalk.org/index.php/topic,24531.0.html
