suggestion: can we have a filter to add some emails/domains?

Love the plugin. Would like to have a filter or 2 to add some emails/domains as an array e.g.

add_filter( 'BSSWO_extra_emails', function () { return ['[email protected]', '[email protected]']; } );
add_filter( 'BSSWO_extra_domains', function () { return ['dangdomain.com', 'notrealz.com']; } );

I figure this is the easiest way … your filter could sanitize input, reject things not matching a regex, then append to the array you use now…
I know filters usually take a param and let you modify it, but that’ll just get messy with people adding incorrect items.
If there’s a GIT I could pull.
