These type of “captchas” look at your browsing behavior. It is sort of a “trade secret” of what it looks for, but it might be screen resolution, mouse behavior, cookies, OS, time to click, etc. Anything a website has access to that would look different from a bot.

I’d really like to see more posts come through, without the dip into the “copy Reddit posts” kind of thing. When I open Reddit, I can read 100 posts of varying topics, refresh an hour later and have a lot of new posts to ingest. Lemmy doesn’t have that much activity, so I end up looking at a very similar “popular” feed this morning, this afternoon, this evening. And 1/4 of those posts will also be in my feed again the next day.
