PHP Fatal error with Moderation plugin (split function)

I tried to save settings on my Network site and got a PHP fatal error, because of the split function in /wp-content/plugins/moderation/moderation.php:265

The split function was deprecated in PHP 5.3.0 and no longer existing in PHP 7.0 (which is what I'm running with). Haven't taken a look at the code itself yet, just wanted to mention it before forgetting about it :wink:
