aliases,...they function in a mult-tied manner.
with the internet in a large percentage of homes,...health, politics, finances, etc., googling any subject one needs information on...and bingo,...its there.
since you can't see behind aliases one never knows who they are really communicating with,..do they.
but when the time comes there is the technology, used from criminals and the government, that breaks through any alias or IP address and bingo,...all the answers.
if you thnk its about bashers or pumpers, well,... lets just say i'd love to get you in a poker game.
