If you want to respond to someones comment, use the additional details section if they have email turned off ... don't give someone who is annoying you ten free points ... jeez.

yeah i know they act like kids....theres one guy who has been doing that to me for 4 yrs and these trolls change their faces to the point where my blocked users fills up and I have to waste time going back to see who is deleted....after 10 accts maybe they should ban them forever...
