...I wonder if there's a programmatic way to detect these bots? Some sort of analysis on their posting behavior?
If they're playing nice they'll have the bot flag checked in their profile, and then maybe build a list of any bot that creates posts? As most of the "good" bots just reply to comments? Anyway just thinking out loud. But I'm thinking I could easily add a public API to my search engine that just returns a list of "posting bots"...
