How to hide a block for specific users using Views? I have a bunch of blocks that I would like to have hidden by default and only shown to specific users that will be determined by a view.

Is this possible? If so, how?
Under the block settings in views, there is an option called "access," which you can use to allow access based off of role (anonymous user, registered user, etc). If your users have specific user roles that you can filter off of, you can use this to do what your looking for.
