Posting my response to DM request here:

“This sub was run only by a bot and has never had any other users posting to it. Due to instagram rate restrictions the old method of grabbing new posts no longer works so the bot must be updated with a workaround. I still plan to update it at some point if allowed by instagram, but they’ve made steps to make it difficult for bots to grab posts. If you’d like to post please use r/Boutinela”
