ok here is the deal i was looking at the want to buy ar 15 thread last month in there was a post about some guy snow skiing and i did not think it belonged there so i reported it or flagged it........ today i got a pm from the person that started the thread calling my a KNUCKLE HEAD and to mind my own business ....... so my question is how did he know it was me that flaged his post ........ he was not the one that posted the snow sking stuff
