Unlike most conspiracy “theories” which are unfalsifiable, this should be pretty easy to prove or disprove. Just search for some random plausibly appealing domains and check to see if they’re registered 24-72 hours later.

It’s not a particularly difficult or clever test to run, so I’m definitely not the first person to come up with it. It’s the kind of thing that’s big news if true but a non-story if false. The fact that no one has found it to be true suggests to me that it’s not happening.
