I think it is just sexual paranoia.

I mean here we are and someone somewhere happened upon a mailing list they didn't want to be on... looked folks up on facebook. Wrote a couple sentances on a blog and we're at "see something say something" and "The author spent a non-trivial amount of time researching the social media profiles and interactions in this group".

That all seems like a huge stretch that could create a situation where all sorts of normal behavior is scrutinized / fingers pointed, etc.
