The get_avatar() function currently lacks a comment ID parameter, rendering the logic ineffective.

In the upcoming version of wpDiscuz, we'll add comments support, enabling you to achieve the desired functionality.

function change_comment_avatar( $avatar, $id_or_email, $size, $default, $alt, $args ) {
	$comment = empty($args) ? null : $args;
	if ( $comment instanceof WP_Comment) {
		$fun_comment = get_comment_meta($comment->comment_ID, 'the_fun_comment', true);
		if ($fun_comment == 'on') {
			$avatar = "";
		}
	}
	return $avatar;
}

add_filter( 'get_avatar', 'change_comment_avatar', 99, 6 );

I'll ask the developers and provide you with an update shortly.

Conditionally changing comment avatar

I'm using a custom field that I added to my comment form and I know from there I can target the meta key with a function. If the key equals a certain value, I want to change or hide that comment author's avatar. The following seems like it should work but it doesn't. Does anyone out there know how to hide or change the avatar within wpDiscuz comments if a custom meta key's value is detected? By the way, I know the custom field is set correctly because I'm able to change the author name, and I was able to add a class based on this custom field. Only the avatar gives me trouble. Also, changing the priority of get_avatar does nothing.

function change_comment_avatar($avatar, $id_or_email, $size, $default, $alt) {
    $comment = get_comment($id_or_email);
    $fun_comment = get_comment_meta($comment->comment_ID, 'the_fun_comment', true);
    if ($fun_comment == 'on') {
        $avatar = "";
    }
    return $avatar;
}
add_filter('get_avatar', 'change_comment_avatar', 10, 5);
