by using their search engine? Sorry couldnt help it.

they could just buy info lists on what you do. they most likely already record all the searches you do on google, so it wouldnt be hard to start there.

I want to know how they plan on confirming ID when they start posting your behavoir without your permission. Someone swiping unsecure wireless, or on someone elses 'puter could lead to unflattering info that seems to come from you. Since employers are already starting to look at blogs and finding reasons to fire/not hire, just imagine what someone hacking your puter and using it as a viagra selling zombie would make you look like.
