Frankenmeshing and community etiquette question.

Hey, so I have become kind of decent at frankenmeshing, and I make a couple now and then for personal use. But my question is, what "rules" should I use for sharing a frankenmesh? I know a lot of creators ask that you not use the mesh in shared versions of a recolor, but is that even possible with a frankenmesh? And if it is, do the same rules apply? Is crediting them enough, or do I need to re-hunt down a link for each piece I include, no matter how long ago I downloaded it? And if a piece is used but I *can't* hunt down the DL link (say, if the person is deactivated or I just couldn't find it), is it acceptable to include their name but give a direct DL link to the original? 

I have never once shared CC before so I have no clue where to even start with sharing etiquette. Any help would be greatly appreciated!
