Anyone know who the company running SimilarWorlds are?

They don't list it here nor can I find it anywhere else, as they're so niche that they don't even have a Wikipedia article. Are they intentionally omitting details to dodge legal accountability? Like if you want to have a legally binding contract, it's gotta be from a legally valid entity. Well you don't have to, but that basically voids the legitimacy of said contract (among other conditions).
