What are all these *_bot accounts on my Discourse that are all TL4, please? 
AI-generated summary
The discussion addresses the appearance of multiple *_bot accounts with TL4 roles on Discourse instances. Richie inquired about these new accounts, while awesomerobot explained that they resulted from ongoing AI work transitioning agents to individual user accounts. These bots were automatically created for all users but can be removed if the AI bot feature or plugin is not being used. A fix has been implemented to ensure users who have disabled the AI bot or AI features no longer receive these accounts.

The tl;dr is that these appeared for everyone due to some ongoing AI work that moved agents to individual users, but can now be removed if you don’t use the AI bot feature or AI plugin
