We don't sell information. We don't track users. (Don't get all huffy, you won't be mentioned in our TPS report either). Quite frankly, we're too lazy to do any of that, and it'd be too time consuming.
Seriously - we do not sell any information, at all that you give us. If this attitude/policy changes, you will be notified via the email address which is in your account preferences. But we really do not ever see this happening.
