Automod suggestion: Blacklist bot accounts from servers that have the same username template

A server I moderate has been riddled with bot accounts with the same username lately, and each one that joins the server looks the exact same, with the same pfp and username template--all doing the same, disruptive actions immediately upon joining, despite tightening security. It just becomes a chore to ban each one that looks the exact same and does the exact same thing.

It'd be really useful to have moderators, admins and/or Automod gain an ability to blacklist or instantly ban certain usernames that match an inputted filter. Unless such a feature already exists, this would greatly help keep away false recruitment accounts, scams or bots instead of either reporting the server being raided or banning each bot account day after day.
