# I really don't like getting routing error notifications when scanners try to
# find vulnerabilities in our application. As such, this extends our routing
# to actually give a response, but it's likely not what they were looking for.
# If they're not using a headless browser, the `alert` is going to kill their
# productivity. If they are, they just might enjoy the youtube video anyway.

Thanks for this! My Rollbar errors have been driving me nuts recently.
