I also scanned the plugin for PHP7 compatibility (with https://wpengine.com/blog/php-7-compatibility-checker-plugin/) and found the following issue:
FILE: /wp-content/plugins/bad-behavior/bad-behavior/blacklist.inc.php
-------------------------------------------------------------------------------------------------------------------------------------------------------------------
FOUND 1 ERROR AFFECTING 1 LINE
-------------------------------------------------------------------------------------------------------------------------------------------------------------------
145 | ERROR | The behaviour of hexadecimal numeric strings was inconsistent prior to PHP 7 and support has been removed in PHP 7. Found: "0x31303235343830303536"
-------------------------------------------------------------------------------------------------------------------------------------------------------------------
Would be great if this could be fixed with the next release…
