confused

I dont often post here but have posted on other boards. I did notice where someone has used my name "bamagirl" on another board and has not been very nice. Why would someone here want to use another persons board name to cause trouble? Have i done anything to any of you for you to do that? Not sure if this is the right forum, but i am very ticked at whoever done this. If you want to have a piss fight with someone, use your own board name. THANK YOU!
