Blacklist causes: warning: redundant nested repeat operator

/Users/{username}/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/obscenity-1.0.2/lib/obscenity/base.rb:24: warning: redundant nested repeat operator: /\bf**k\b/

This started popping up after I added a custom blacklist (goes away when removed).

It fires off every time text is evaluated, which - in my case - is ~100 times during my test suite :)
