Hmmm...maybe people do stupid searches on them. I was looking at the google searches people come on my site from, and noticed a good one: x x x stuff (without the spaces of course). I promptly opened it, and...wow I'm in 7th position, all thanks to a masked email address in my post on the J editor. Due to insistent requests from my gf, I changed the email address to to show z characters instead of x.
