      Hi,

      The custom CSS in your account settings is invalid and has been removed from your account. To restore it, go to https://codebeautify.org/cssvalidate, copy and paste the CSS below, and fix any errors that are shown. Then, go to your account settings at https://danbooru.donmai.us/settings, click the Advanced tab, and re-add your custom CSS.

      [code]
      #{user.custom_style}
      [/code]
    EOS

    user.update!(custom_style: "")
  end
end
