I made 2 separate posts into 2 relatively dead communities, and despite getting a decent amount of traction (relative), the first 2 comments in each were 100% negative towards the content.
None of the commenters had ever posted content to the respective communities.
Content deleted: c’ya!
Totally this. If every content creator succumbed to the negative comments, there would be no content. Just ignore them, or say your peace in response if that’s what you need to do.
