“Anchor + Offset” is stable because the anchor param should uniquely identify a specific record from which the offset is applied; a sort-order, direction, and page-size may also be optimally specified.
The only stable way to share what you're seeing is with a screenshot.
It's addictive. There is no "one more page and I'm done" because the page never ends and you're never done. You get to the bottom, more content loads automatically and people say "this looks interesting, let me scroll some more". That's why it's doom scrolling because all you do is scroll, no need for any other input. The bait is always there right in front of you and I'll bet that the algorithm make sure the first couple of posts that load every time you get to the bottom are the "juiciest" ones to make sure you take that bait and keep scrolling.
Pagination hides the juicy bait. It's still there waiting for you but it's hidden until you ask for it. That's a big difference.
