  # Our architecture didn't allow us
  # to customize message body in a right way.
  # That is why we fuck it up right here.
  def fuck_short_url(text)
    return nil unless text
    # Offer short url in email should differ from generic one
    # Additional parameters should be included:
    # share_specific_short_url includes {source: 'email', email_shared_with: email}
    # Sometimes we can not avoid this hack because of the following usecase:
    # When user is sharing offer via email though talkable offer page
    # Email body might have a link within.
    # For example user sees the following message body:
    # "I can get you $25 off with this link: http://www.talkable.com/x/Uk6EX"
    # In "Share this offer by email" form
    # But this link doesn't yet know the email person wants to share with.
    # And we are not able to set a placeholder
    # That is why we need this hack to replace it.
