I'd argue that Reddit leadership, which insulted, hobbled, and wrote off its mods and power users (destroying projects like /r/BotDefense) while doing little to crack down on the proliferation of bot repost content, had a major role in encouraging this. They might even like it better this way -- lots of extra fake engagement boosting traffic stats without messy human drama, which they can then ironically sell back to AI labs as training data.
It was bogus even before that. I heard complaints at some point that API changes broke bots, which actually sounds good.
Let's never forget the summer of 2023 when Reddit forceably removed mods from many major communities and replaced them with corporate shills. That was a major loss of dedicated people who cared more for their communities than Spez's pocket book.
