How to delete/block a list of users contained in a CSV file? I'm looking for a solution that allows me to delete/block users from a CSV file.

Here is more information of the solution that I'm looking for:

I have a CSV with a list of users that are spam or not responding to emails. I would take that list and give it to a Drupal module and corresponding delete or block or make inactive users.

Ideally, it would work like logintoboggan:


Disable the account and keep its content.
Disable the account and unpublish its content.
Delete the account and make its content belong to the Anonymous user.
Delete the account and its content."


User should be able to set that for the batch.

How can I achieve this? If there is a module that can take me to a similar direction, that would be fine too.
You really don't need a CSV; all you need is the identifying column (e.g. mail or uid). To that end, you have one option  with the Bulk User Delete module.


  This module allows you to bulk delete users through the admin
  interface. You provide a list of email addresses, one per line, and
  the users are deleted using the batch processing API.


With this module, you can grab your mail column to feed into the interface to bulk delete.
