based on the list of instances made by @sunaurus@lemm.eehere - Thank you again for that work, it's highly appreciated.
This is a preventive measure against massive amounts of accounts being created for botting purposes. Most instances banned appear to be 1 user instances so we don't think this will have a great effect on anyone's usage of Beehaw. If you are an admin of one of those instances, feel free to contact us at support@beehaw.org
Side note, life has been so much better in my feed since defederating from the instances that were becoming furry/gonewild heavy. Thank you for your diligence.
