It's flagged because its historically not Hacker News. Many of the newer accounts seem to bias towards using this forum as a "reddit" to discuss how much they hate the current administration or their mental issues. The technical "hacker" content is getting less and less -- thank God for https://lobste.rs/. So that's all fine and maybe hackers should just change be a reddit forum, but don't take it personally or be surprised if 15 old accounts are flagging your posts. I say this noting that the account you posted from is only 9 months old.
