This is something I've noticed in general with social media.

Posting too much can actually have a negative effect on your ability to influence people with your message. I've had friends who post political hot takes dozens of times a day from both sides of the political spectrum. Rather than have the intended effect of influencing me, I block them from my feed.

Ads are subject to the same problem. Too much and the ad blocker goes up or I leave the platform.

There is a sweet spot to how much you post if you want people to pay attention.
