I was not involved in that. The team account we have been using is the @Emercoin_EMC account.
I previously messaged the owner of the @Emercoin account. He was not hostile to me, but he would not tell me who he was and always retweeted what I wrote (which was good) however this was months ago and I have had no involvement with the owner of that account since.
I will check with the other team members to see what has happened on Twitter.
