@mekkaokereke I wonder if shared moderation team could help. Like a moderation panel that could handle report for multiple instances and a few small instances that help moderate each other instance using such a tool. This way, a dozen instance have one mod available 2h a day, instead of being unmoderated 22h a day, could be moderated all around the clock.
In the past, spam filter have been used to classify text content. Maybe it could be done for triage in moderation.
