Not only is my SJCX at Poloniex "temporarily disabled" (for weeks on end), I received the message this morning that upon logging in I have committed Error 1015 and an being "rate limited." The owner of the website (poloniex.com) has banned me temporarily from accessing the website. All I can say is: if the website owner continues to comport himself in this erratic manner, he will soon find himself without any customers at all.
RE: Why are certain Crypto-Currency becoming temporarily disabled in Poloniex? What gives?
