I tried posting my story-with-self-promotion (self-association indicated at the start of the content) to several subreddits. Most explicitly outlawed self-promotion posts, so nothing even got submitted there. The few that didn't got instantly hidden by auto-moderators, pending review. Out of those few, my DMs and followups to mods to kindly consider my post got a vague 'no excessive self-promotion' message (to my only post) days later, then got ghosted after.
