I'm getting suspicious, but it's not enough to flag them as spam.
Is further inquiry possible and necessary?

I have not yet commented asking for possible affiliation.

Good find Jan. I've "protected" the upvoted question (one, two) in the meantime, to prevent new users from answering.

Yeah, sort of grey area regarding spam. Either way, we should downvote until they are hidden - because there is no actual open data and the answers are low quality (basically link only).

And the authors must disclose affiliation, so please add that as comments.

Mod Note: I can add that users 2 and 3 have IPs that resolve to the same Eastern European country. The first user has a geo-scattered IP.

  • What's a geo-scattered IP? My Google-fu fails... You mean an IP that's known as a VPN exit server?

  • I just made it up. As a mod I can lookup IP (my activity is recorded), and the first user had an IP that isn't clearly defined to one geographical region (each lookup provider gives a different answer).
