I see lot of user accounts are being registered on my Ruby on Rails app every day, since weeks. Almost none have confirmed there email address when they received the confirmation email, so I think it is a bot which is registering real email addresses from some database.
How can I put a protection to avoid fake account registration? Without Javascript?
And, what is the reason for a bot to do this?
@KillianKemps perhaps rack-attack can help https://github.com/kickstarter/rack-attack
