Rails understand this as creating urls like rmagick/123/download, i.e.
it things there are actual rmagick entities which supports a download
action
This means that when you call download_rmagick_path rails is expecting
you to supply it with the id of the rmagick entity. If you don't rails
won't be able to generate a url. You'd probably need to either switch
to a singleton resource, make those actions collection actions, use
match rather than creating a resource. The rails routing guide should
explain the difference between these actions

That's what it's supposed to do - given the routes you've defined, /
rmagick/jjvniuv is the path for the rmagick entity with the id jjvniuv

I'm surprised it does anything at all. You've got the same problem as
earlier - a route that is expecting an id, but you're not giving it an
id.
You might also want to look at the recaptcha captcha - it's very easy
to integrate
