A: We’re very careful not to include cards that don’t play well together in a deck. So, for most decks with Creepers, we use Mix It All Up (or one of its analogues, like Crawling Chaos) instead of Share The Wealth. Star Fluxx doesn’t have either card (Share The Wealth OR Mix It All Up). The only deck with Creepers that has Share The Wealth is Pirate Fluxx, which does not have attaching Creepers, and Crawling Chaos (in Cthulhu Fluxx), which includes Creepers but specifically says that you do detach Creepers to mix them up, so that should be clear.
Mix It All Up is clear in its wording that it will detach Attaching Creepers, in that it says to gather them all, and when redistributed “Creepers that attach are attached to a new Keeper…” We don’t want a “memory condition” to exist where you have to remember what a Creeper was attached to when you mix them all together.
If you’re encountering Share the Wealth with Attaching Creepers, it would only be if you were mixing decks, in which case, please treat it as if it were a Mix It All Up card: detach all Creepers, and mix them all in with the Keepers to deal out. If you’re just playing Pirate Fluxx, it should not be an issue to play Share The Wealth as written, i.e. not including Creepers.
