I’m curious as to what rules were broken? You mentioned ‘somebody complained’ but that is surely not enough for the bot to remove your post?

I don’t like cancel culture but I don’t see anything wrong with your post at all. There’s no obvious issues (sexism, swearing, harassment, etc.). It’s written fairly respectfully. So I don’t really see what grounds there are for removal (I don’t know, and haven’t checked the posting rules for your instance though).
