There are a few options missing. I would vote

"I no longer trust Facebook, but continue to use it regardless"

Nowadays I use Facebook primarily as an instant-messaging protocol, just because it's so convenient. I've effectively disabled my news feed by manually (well, with a script!) clicking "hide all from this person" on every post, and never post anything I don't also post on Twitter.

Wow, a push-poll on HN. Nice. Flagged.

What about the, "I never trusted Facebook and continue to not use it." option?

I wouldn't trust the results of such polls given the fact a user can vote more than an option.

I have never trusted Facebook with my personal data and I have never had an account in the first place.

If we're going to have polls like this, can we at least use proper questions? These, and the other one's questions are compound and weighted toward lack of trust. This is a solved space.

I've never been an heavy Facebook user, so even if my account is pretty old I've never feed it with much data. All I use it for today is to talk to some friends that refuse to use something else. Maybe I might give a quick read at my wall if I'm really bored, but that's it.

Regarding trust, I trust Facebook as much as I trust other free (as in beer)/closed systems: "If you're not paying for it, you're the product".

This poll should be broken into three separate questions:

- Do you trust Facebook?

- Has you usage level increased, remained the same, or declined?

- Did your trust level impacted your usage?

"I never trusted Facebook (or any other site) with my personal data, but continue to use it as much as before regardless."

I find it much easier to accept that all information is eventually public, and not really worry about it.
