Everyone always says this, that there's "bots" all over Reddit but every time I ask for real examples of stuff (with actual upvotes) I never get anything.

If anything it's just the same regular spam that gets deleted and ignored at the bottom of threads.

Easier content generation doesn't solve the reputation problem that social media demands in order to get attention. The whole LLM+spam thing is mostly exaggerated because people don't understand this fact. It merely creates a slightly harder problem for automatic text analysis engines...which was already one of the weaker forms of spam detection full of false positives and misses. Everything else is network and behaviour related, with human reporting as last resort.
