long time no post

sorry i havent posted in a while  but oh well. i decided to become more active on deviant art and i added a few more pics but i added one that a fellow fma fan said she had drawn and i put it on my profile rite and like a minute later i check my messages and these girls are yelling at me to delete it saying u can't post things that someone else owns and im thinking my friend said this is her picture! but the kept hounding me to delete it! so i deleted it but they still won't leave me alone! what do you random blog lovin people think i should do?
