The spammer next door

My LJ allows anonymous comments, but lately, it's been abused by comment spam.

Makes me wonder if I know spammers in the meat world. I mean, have I waited at a traffic light with a spammer in the next car?

Have I browsed the computer book section and said "pardon me" to a spammer as I'm reaching for a Peachpit book?

Have I bumped into a spammer as I'm scanning the Ethernet connectors at Fry's?

What do spammers look like? Are they rich? Poor? Nerdy? Male? Female? Foreign? Domestic?

Is there some sort of spammer profiling I can do the next time I'm out and about so that I can kick the ass of the next spammer I encounter?
