For context, the post I'm referring to is a map of Africa with subsaharia Africa in deep green, Sudan in light green and north Africa was white or some other color. The poster was claiming nothing had ever been invented in the green zone. My comment was gonna be this:
Antiseptics before Europeans.
Iron Smelting Not the first to discover it, but recent evidence show it was invented independently.
Some modern Archtecture taking inspiration from Sudano-Sahelian features such as a roof shape favoring natural ventilation. And since I just transitioned to recent inventions, there's the Cardio Pad, invented in Cameroon, to help diagnose cardiovascular disease.
The people who saw the post before the "correction" are not likely to ever see it, and since it's deleted no one else is going to see it and won't benefit from the "correction"...I simply can't see why this causes distress unless you're really just doing it to correct someone and feel superior, and the deletion robbed you of that.
As I said, the frustration comes from putting work into a comment you can't post (with the intention of posting it under the post they didn't know it was deleted) and after already putting the work into the research, why not post it somewhere else instead.
There's at least two people in the comments who testify having seen the post I'm talking about. If people who upvoted these comments are people who also saw it, then that makes 16 people.
I think people who saw a post on a specific community have a decent likelyhood to see a post made a few minutes later in the same community. This is Lemmy, feeds tend to be relatively slow moving.
