I have been told that you can't use oil with moly in a wet clutch is this true?

Yes, that is true. Any kind of synthetic oil with a Moly-additive has been specifically designed to eliminate as much friction as possible, so you definitely don't want to run these oils in your clutch. Having said that, if your motor oil is separate from your gearbox oil (take newer Hondas, for example), you could very well run this Moly oil in your motor and see no "side effects" of the Moly-additive since the clutch uses separate oil. However, I personally don't think I could recommend running any of these Moly-additive oils. When in doubt, I'd just have to suggest running whatever oil is recommended in your bike's owner's manual!

Yes it is true, because it is too slippery to run in the clutch.
