Hey @russellsmithies!!
Thanks for the pointer; that article is actually out of date! Locking users is still completely feasible / recommended and does open up / frees license seats. I.e. a locked user will NOT count against your license. Note that users can now be locked using the RStudio Connect Server API (e.g. programmatically while the server is running):
https://docs.rstudio.com/connect/api/#lockUser
There is also now the ability to delete users (in RStudio Connect version 1.7.2 or later) using the usermanager utility. Note that users who own content cannot be deleted until that content is migrated to new ownership. Further, all audit log and instrumentation information (i.e. information about what Shiny apps they visited) will not be deleted, but will no longer be able to tie / reference to an actual user. How to do so is explained in more detail in our docs:
https://docs.rstudio.com/connect/admin/user-management.html#removing-accounts
https://docs.rstudio.com/connect/admin/cli.html#cli-usermanager
I would recommend locking those who have left the company, and deleting the misspellings.
Thanks for reaching out!
I will make a note to update that support article!
