Filters the list of a user’s sites before it is populated.

Returning a non-null value from the filter will effectively short circuit get_blogs_of_user() , returning that value instead.

$sites null|object[]

An array of site objects of which the user is a member.

$user_id int

User ID.

$all bool

Whether the returned array should contain all sites, including those marked 'deleted', 'archived', or 'spam'. Default false.
