It takes two steps for a thread, eg a welcome message on a spam user's wall, to be removed. Step one: "Remove", step two: "Delete".

When a thread is removed from a wall, it becomes invisible, and if you're not quick you'll have to do some extra clicking to delete it. That little CSS was designed to prevent it from being made invisible by the thread-removal script, however it ended up not working. So User:Princess Platinum wrote a tiny bit of code which is now in User:Thisismyrofl/common.js to do the same thing, and the code in the page you've linked doesn't do anything.

Note that VSTF have the "wallfastadmin" right which lets them delete threads in just one click, making the code pointless. I asked for Central admins to also get this right, but it glitched >.<
