Yeah repetitiveness is quite normal, you see YouTubers and other content creators outside of hive do the grind too, here you gotta at least work on your audience to show that you care about the community you're in many ways taking rewards from or else consistently posting and grinding on reworded content (even if reworded from yourself) might seem a bit much that some may want to adjust if you're taking a big chunk from the pool.
As mentioned these are usually quite small in rewards but it's still kind of a problem considering they're literal copy-paste in content and how you can participate is mindless, take no effort to generate and finalize and most often the rewards are 5-20x the thing they're giving away.
