I noticed that spoilers don't work, so I looked into the code, to try and find out what the problem is. Unfortunately, I can't find the bug in the Javascript, but there is a pretty easy tinker users can do, in Firefox and Chrome, to make spoilers visible:

1. Install an add-on called Stylish. It's a lightweight add-on that can be used to change the way any website looks/behaves in your browser.
2. Go to the add-on's Options page, select "Write New Style" from the left panel
3. Copy/paste the following into the Code section: div.UserSpoiler div.SpoilerText{ display:block !important;}
4. Save your new style (you have to give it a name, first)

This will display the content of all spoilers, automatically. Note: if all the extra pics/vids slow down the page load too much, you can easily disable Stylish, or the individual style you created, and spoilers will be hidden again.
