The Predator mod has not been approved because it contains copyrighted music taken directly from the movie soundtrack.

The Justice League mod has not been approved because it contains large amounts of graphics directly out of the base game (making them available to people who don't have it) as well as unattributed content from other mods.

The Farscape mod has not been approved because it contains copyrighted music taken directly from the soundtrack, images of actors (most very likely copyrighted) and also contains unattributed content from other mods.

I don't see any stargate mod by you in the list. The Runes pack is on hold due to all your other mods containing copyrighted content--it looks like you just did a google image search and saved what you found?

Both of those still contain content they shouldn't.

The AVP mod has a wallpaper (with a notice on it specifically prohibiting redistribution) and images of actors (those are specifically prohibited on the mod upload page).

The Star Wars mod contains the entire opening sequence from Episode IV. I didn't look any further at it than that. I hope that you're starting to understand what sorts of things can be allowed in the library and what can't by this point, though.
