Shadowbanning blocks comments from being seen by some, possibly all, users. A person posting a comment, seeing it, may not realize it is blocked from being seen by others.
Joe Sempolinski is running in the NY-23 special election. He posts campaign material on facebook. Which comments on his posts I see depends on the facebook account I use to view them. In every case I chose “All comments,” which matters. Here are some examples:
Post | Comments reported | Seen on 1st account | Seen on 2nd account | Text not seen on 2nd account | |
| Biden’s Price Hike 6/11 | 1 | 1 | 1 | ||
| Inflation would be transitory 6/11 | 7 | 7 | 7 | ||
| Back the Blue 6/10 | 7 | 6 | 5 | Cop who shot unarmed man in the head back in April has been charged with 2nd degree murder. | |
| Unacceptable- vote for change 6/10 | 2 | 2 | 1 | A 4-month congressional paycheck of $58,000 would be great wouldn’t it? That about the average family income in the 23rd isn’t it? | |
| There should never be a baby formula shortage 6/10 | 5 | 5 | 5 |
More comments than those recorded above are unseen if “Most relevant” or “Newest” is selected. What I see changes from time to time. The above data was noted at approximately 16:00 on June 11, 2022.
I don’t think Joe is to blame for the shadowbanning. I think facebook is choosing what is visible based on which account I use. I can’t see one comment on “Back the Blue” with either account; perhaps it was blocked for all users.
New NY 23rd 
Interesting. Are you planning to ask Facebook for an explanation?
