Regarding the previous reports of issues with bots, I found that following the installation of this extension, the Google indexing on my sites has dropped to near zero, accompanied by Google search analytics.
I found that there is a bug in the extension:
In listener.php at line 290, the test
&& !$this->user->data['is_bot'] needs to be added, otherwise the bots are all redirected to the agreement page.
You can test this by putting a bot user agent string into your browser (instructions at:
