Go, have your fun, experiment, fuck around, push boundaries. Don't make profiles for me based on info you found, public or not, and then sign me up to receive notifications for messages on it without my permission.
Yeah, Facebook started in college, but it didn't start with scraped data and auto-generated profiles.
Facemash, Mark's pre-facebook project, was a page to vote on student attractiveness, with names and pictures of female students scraped from Harvard.

I suppose it would be worse without the notifications, even though they are form of spam, because then you wouldn't know what some anonymous posters are writing under a purported profile of yours.
