Hello! Poloniex staff here. I'm not sure who manages your twitter, but
https://twitter.com/PoIoniex/ is not the real account. They are impersonating us, using an "i" instead of an "L". Please unfollow them and instead follow:
https://twitter.com/Poloniex. We are in the process of having the account disabled by Twitter. If they requested you pay them in order to have your coin added to the exchange, do NOT send them any funds. The only way to have your coin added right now is through the Coin Request form here:
