title: How to ignore routing error with wrong verb
body: <p>I have a few POST actions. There are always stupid crawlers trying to ping those actions, resulting in "No route matches [GET]" errors.</p>
  
  <p>There are too much of them, and most of them are purely noise. How can I make it so this kind of error messages are ignored.</p>
  
  <p>I used to use exception_notification gem, and now I use rollbar gem. The amount of these kind of trash error message always floods my error monitoring (either lots of messages, or too much error api calls).</p>
