If you're using Firefox, you can download the "Stylish" extension and use it to force all spoilers open. The CSS to do that is:
Code:
@namespace url(http://www.w3.org/1999/xhtml);

@-moz-document domain("giantitp.com") {
  div.quotecontent > div {
    display: block !important;
  }
}
With that turned on, all spoilers will be start off open, and cannot be closed.
