Anyway some of the sites listed are no longer working so you did a good job here, maybe some of the sites got taken down. People reading here could also check from WHOIS data who the domain registrar is for these sites and report the same, who knows, maybe one or two gets taken down.
Unfortunately, it's not happening anymore with all registrars the rate at which the above was taken offline is quite extraordinary.
I've discussed this with some other users on a topic, everyone wondering why the domain name was still active and the overall consensus is that domain registrars aren't doing anything anymore about this. There are clear scams, obviously Ponzi schemes, with wrong and tock photos, even with identity theft and NameCheap for example is just silent about them. A few years ago they were quite active in suspending domains but nowadays the whole thing has changed, probably they are far happier with the $ than with the bad publicity. None of my reports in the last year had any effect so I reluctantly quit doing so.
From the list I see that there was one drop before expiration with whois history, that was as com domain from godaddy, probably they are paying more attention to the more used .com extension than to the other garbage.
I feel that there is also a communication gap in this forum. Users who usually hunt such airdrops and land up on such sites are usually regular in sections of the forum that do not include the "Scam Accusations" section which is a vital part of this forum. They usually come here after getting scammed.
Just as most people don't go for medical check-ups when they are still healthy but only when they can't stand on their feet without help.
