Notice 6 or 8 threads are blank and say moved.
Why is this and where do they go into the forum abyss??

 

They're usually a topic that's better suited in a different section, most are "off topic" for a forum section,, so a moderator will move it to a section they think it belongs.
If you click on the "Moved" part, it will forward you to that topic in the new section.

 

Bad boy, Bad boy, whatcha going to do when they move your thread on you....
