Exclude users from view_all_users

[Moomintroll]

Is there a way to exclude certain users from the results shown on the view_all_users page?

I've looked over the site using various search terms but nothing seems to address the issue.

I need this for two reasons:

First, although GDPR requires a 'Forget Me' option, if a financial transaction is made there is a separate requirement to keep a record for 10 years (I think), so straight deletion is not an option.

Second, for similar reasons, it would be useful for active members of a society to be able to withhold their names from such a public directory (even one that is restricted to other members).

I'm reasonably sure I can create a column in the users table that could contain a 0, 1 or 2 code, but its the retrieval query in the view_all_users page that I'm stumped by.

I've found these lines:

Code:

$userQ = $db->query("SELECT * FROM users LEFT JOIN profiles ON users.id = user_id ");
// group active, inactive, on naughty step
$users = $userQ->results();

...but I'm not sure what they're doing.

Cheers in advance!
