Yes. I understand there's some controversy with some things mr Saylor has said recently but I do remember him speaking quite eloquently about this issue and one solution in the form of what may be called an "orange check" that internet money like bitcoin can provide. I don't see any other practical way to stop spam myself. And it's just so friggin' simple, easy to understand and seems like it can't be that hard to implement. I don't understand why more websites and email providers haven't begun offering this feature years ago.
I guess that bigger network effects are needed to make it a viable solution and it may not be worth the effort for these websites given that so few people own btc, and an even smaller fraction lightning. Then again it wouldn't have to be bitcoin perse. As long as there is some cost. Could be X tokens. I'd have hoped that X would have been one of those trailblazers by now helping bootstrap initial network effects and introducing the idea, seeding the zeitgeist. Of course they've got lots on their plate as well so can't blame 'em that much.
In early days when you turn on "orange check mode" nearly everything will be blocked since so few people have set up the payment rails but the way to get it to catch on I'd think is to offer the ability to turn on "orange filtering" or just "money filtering" client side and have the user be able to select treshholds and amounts and also have sensible default settings.
