Trolling is an ancient problem. It's been around as long as there has been media.

Wikipedia, a nonprofit, is an enormously popular website but has managed to operate without advertising. And, you know, maybe it's a little simpler than Google and YouTube, but it does show there's another way.

If you have a disease and suddenly start getting ads for cures for that disease and it's an embarrassing disease - all that kind of stuff it just gets into that zone of autonomy or privacy where you feel a sense of freedom to be who you want to be.

When you pay for stuff, it has more of your interests in heart.

When you decide to like something, I mean, you may feel you're sort of innocently putting out your preferences, but actually you're delivering something of enormous value, which is indicating that, you know, you'd essentially like to be advertised to by this company.

The blessing of the state, implicit or explicit, has been crucial to every twentieth-century information empire.

You know, it's so funny that the internet's become a series of traps where you do sort of innocent things like give your name or address or indicate a preference, I like this thing, and then therefore you open yourself up to a deluge of advertising based on those stated preferences.
