@emacsen Hi, that sounds very interesting! I’ve implemented a pretty simple rule based approached to help detect spam posts on pixelfed, basically every post is run through this queue job and it bails early it a non-spam condition is met and if it reaches the end it’s likely spam which gets flagged to admins to decide to re-list or delete https://github.com/pixelfed/pixelfed/blob/dev/app/Util/Sentiment/Bouncer.php
