livestream troll?

Hey. I was in a livestream at livestream.com, with a person drawing. her name was "mel" in the chat. Her full name on another site, was there posting, which was NOT her. and it didn't say anyone changed the name to that. and it said the full name was a moderator. yet it wasn't her. and like she has "mel" and was a "User" as she was posting under that in the livestream. then later that creep POSTED AS MY NAME! I didn't say anything but it normally if someone changes her/his name on Livestream it says "xxxx changed name to xxxx" but it didn't say anything like that when it changed to my name and posted under it, while at the same time I had it.
What was going on? how did he post as an moderator? and the person livestream didn't find it funny when he was using her full name on another site. so it deff wasn't a person she knew.. and how did it change to MY name without showing anything? and posting under it at the same time? Was it hacked? or wtf!!!!

and if so , how do i do this?
