RE: Accessibility suggestions

Yes, a good idea. I would like to add an option to disallow anonymous access. Also options to only learn from administrators, or trusted users.

Currently you can create your bot as private, and control who has access to it. I will look into adding an option to not list a bot in public.

You can also disable learning, or disable correction from the Learning page under admin. Then your bot will not learn from users, only from its administrator.
