If you mean posting on one of the existing moveset questions, No, you won't get flagged. The whole point of the moveset pages is for people to post movesets and for others to improve them. Saying specifically that you want help with your set is fine.
Though don't be disappointed if nobody says anything. It just means that not many people have seen it or others didn't see any problem with it.
However, asking another question will get you flagged.
