Blocks search bots! Don't install!

After I installed and enabled the module googlebot and other search bots couldn't access my website. They got an error:
Status: HTTP/1.1 500 Internal Server Error
I got deindexed from google after 7 days! Good thing I found out on the same day and figure out the faulty module. After disabling it, googlebot can access my website. Let's hope rankings will get back.

Don't install this module!
