Can I bring about a few examples, and if possible, get staff's opinion on allowance of:
a) A model replacement ported from non-Valve game. Say, Mario was ported over and now replaces Coach.
b) A model replacement, ported from a game developed / co-developed / published by Valve.
c) This one is more detailed: say, there is a mod (there actually is), that replaces pain pills item with a beverage can. The model/texture/sound is a joint work of several authors, everything is custom. However, the label features (not resembles, but absolutely the same) a logo that is a registered trademark, say, Pepsi (and thus is intellectual right blablabla).
d) Finally, a music/sound replacement. This is something that gets restricted the most on other sites, even if previous examples are ok. Well, Benny Hill's theme for Tank probably isn't that much of infringement, but how about well known songs, movie themes and soundtracks from other games?

I think the answers you're looking for are in section 4 of the Workshop Contribution Agreement:

No nude mods, please. "sexy" is subjective enough that I can't give you a blanket answer.

Hi guys. I think we actually have a problem other than the file size issue that we're investigating right now. There should be no wrong way to split up the .vpks as long as you have all the right ones active and don't have conflicts with other mods. Could you try uploading a very small one just to confirm whether you can upload at all?
