Did that woman make a specific threat though? Lots of people say Fuck Zuck on the internet, but it sounded like they restricted it to people who got specific or had other reasons (fired employee, contractor who's mad their contract wasn't renewed).

The idea of a blacklist makes me uneasy, but for example I will state on the record I think Mark Zuckerberg is a big doo doo head, but I don't think if someone tied this nym to my real name I'd be banned from FB's campus.
