I think this would be more effective on the fediverse too, bots are trying to engage as wide an audience as possible, which gives us a metric to monitor activity across the fediverse.

For example, a user might post an article to the news community on their preferred instances whereas a bot will unbiasedly post it on all instances it deems fit to share with.

This isn’t perfect but it’s another metric to help weight and quantify bot activity for an automated defense system. RSS feeds and the like can specifically flag their accounts as automated to avoid misbans from the system too
