I look at inception points and loci. When I start seeing the same talking points or information repeated almost verbatim from different accounts on different sites that, generally, either cover the same subjects or overlap in the Venn diagram, I get interested in seeing where they originate. So I ask for a source. Occasionally, I'll get one only to find it's a repost from some other article that is posted. You follow that back and realize it's a single source just being propagated automatically,
What sticks out are the bizarre sentence structures, grammar choices, and clumsy wording. Can humans do that? Sure. In a whole article consisting of multiple paragraphs? Ehhh...odds would say no. So that tells me bots are scraping and reposting without human intervention. Which is making the Dead Internet Theory slowly morph in to existence.
You have a far more optimistic and charitable view of the modern day internet than I do. By a very wide margin. What I see the internet now as is a cesspool largely dominated by the ever sucking maw of greed. Sites like Imgur and Reddit completely twist themselves in to unrecognizable shadows of what they were to chase the a'mighty dollar. The quality of the content visibly degrades and, so too, does the amount of useful information and interactions. YouTube is another fine example of algorithms and money causing humans to do ever more stupid tricks to try and gain relevance. Hence the stupid mugging on video thumbnails and clickbait titles.
What I don't see that much of is in decentralized networks like Mastodon and Noster. Definitely smaller userbases than the established players, absolutely, but because no one corporation owns the means with which to interact, people take a very hard line on bots. Especially since the power to control what you see is wholly in your hands. No automated feeds shoving weird or conspiratorial nonsense in your face. Just the people and subjects you want to connect to and with.
