I used to use a bot in one of my communities to help me out. Turns out it spammed way too much. Once I got feedback from the community I turned it off. I now have sources fed to me privately via RSS and then filter content based on what I think the community will enjoy and post it manually. Is it harder? Yes. But the community has more engagement, comments more, and votes positively more often since I started doing it this way. I also gain consistent new subscribers daily. I also have control over the “nozzle” so if multiple stories are worth posting but there are too many, I can sideline some for when the news slows down and post them later.
