Deleting multiple users in bulk

[Moin]

@Discourse

Manage permissions with groups: Instead of assigning permissions on a per-user basis, use groups. This makes managing access to categories and features much more scalable and organized

How would I do the former in Discourse? Can you assign permissions on a per-user basis?

@Discourse

Don’t let inactive users linger (indefinitely): While not always necessary, you can establish a policy for deactivating or anonymizing users who have been inactive for an extended period, especially if they have no posts. This can be done to respect user privacy or to keep your user list tidy. The delete_user_max_post_age site setting can help automate this for new, post-less users.

What is the connection between deactivating or anonymizing and a setting for deleting users? I thought deactivating or anonymizing doesn’t delete posts.
