I'm more worried about stalkers, psychotic exes or angry twitter mobs being able to buy this data.
I agree on this point - there is an important distinction here between "frequently" and "always". We should be vigilant indeed and seek to uncover the true purpose of those who are malicious and deceitful. The previous remark should perhaps be taken more as a statement of relief, that fortunately there is often an inverse relation between maliciousness and intelligence.
Maybe I don't want to become a part of this community after all.

edit2: what's with the lack of transparency?
