I suspected from the tone of their post it could be trolling, but I happened to be only two jumps away as I was doing other experiments nearby. So I thought, fine, I'll bite, and take a look.
So far, nothing unusual to me. I've tried both light and dark sides of the planet.
The most interesting POI discovery was an uncharted outpost/facility/buildings with some canisters, but it just seemed to be standard POI RNG stuff. http://imgur.com/tNITlNY

Explored a few more POIs, repeatedly going to orbital cruise and back. Some crashed ships, some scattered canisters, one downed satellite dish (not the nav beacon).
Most interesting terrain I found was a canyon network with a large crater intersecting it. http://imgur.com/YboLqHg

This place was great fun to explore in the buggy, but there's no tentacles/barnacles/Jehovas Witnesses here. There were a number of POIs here, but just appeared to be standard POI RNG stuff.

It's a big place, so I have by no means explored it completely and could easily have missed something of course. There is a huge shallow (relatively) impact crater on one side of the planet which I will check out next, but if that turns up more of the same I'm going to go back to my other experiments.
I did a quick skim of the large crater, nothing stood out as being out of the ordinary. I'm going back to my other experiments until any explanation of why this planet is special.
