Not sure if any of you guys will find this helpful, but I put a guide together based on a fake I got sent off MUA. I wrote this guide for her to help her spot them in the future.
This is info on the 'good' fakes - part of a new batch. There are several older batches which look F-all like genuine pigments but these babies are harder to spot. This is mostly pro-specfic - non pro fakes usually have left aligned text and (convincing) silver labels.
The fake box is always on the left, but the fake pigment isn't (I was in a hurry, stupid move, I know!).
Points of note

Usually I ignore the wording of the writing on the box since MAC change this element of their packaging so often. What is worth picking up on is how lovely the box is. If you feel them the cardboard is very smooth and sturdy. It is *really* hard to scratch/dent/batter them. I store a few of my boxes in a drawer where they get battered and they're not bent in any way. The fakes are nearly always bent. In this one it's a bit stained and the shiny 'overlay' has come away. (The bubble on the top left). This never, ever happens with real boxes and is a dead giveaway.
The text on the fake boxes is thicker. This is usually most evident on the weight info on the front of the boxes (and here on the section beginning 'dist. by' - the book logo is also much thicker). In ebay auctions you can often see that the font is too thick if the photos are high res enough.

Sorry for the rubbish quality. The bright fuchsia was bought from MAC a few years ago. I used it because it's an old-style jar (centered text - the new ones are left aligned and also often faked, but that's a whole other guide) and the colour is bright so hopefully you can see the text. My camera hates close ups.
It's so hard to see but the left reads '' M•A•C PIGMENT COLOR POWDER' Whereas the fake is 'M - A - C'. This is a feature on every fake I've seen in this batch.
The text is bolder, more angular, and more 'dense' on the fake. Again, it's a bit hard to see but a difference is visible. It's also more 'obvious' - the genuine one is a few years old and the text does tend to rub off / 'fade' a little with time.
On this one the lid isn't shiny but it is a tiny bit taller.
FWIW, if you can see, on the jar it says 'made in canada' but on the box 'made in USA'.
Mattes are usually 2.5g rather than 7.5g. Not always, but it can be something that alerts you to other issues.

Pro pigments always have clear labels unless they're pre-2000. Fake pro pigments nearly always have these cloudy labels. Often, as here, the text is also more angular. Pay attention to the batch code - the final digit is the year it was made. As you can see, I bought my bright fuchsia a while back (2003 - the batch is usually a year or so before purchase). Is it really likely that a 2003 (AA3) pigment would pop up new on ebay in 2010?
Sometimes on ebay it can be tough to see if the labels are cloudy, but ask for pictures. Usually the seller will tell you if it's cloudy if you ask - the vast majority don't have a *clue* that they're selling fakes (they just believe their infamous 'suppliers') and so will happily give you this info without realising they're betraying fake pigments.

Not all pigments have inserts, but most do. Every fake in this batch has a photocopy of the insert on the left. It was a genuine insert, but for the MAC non-pro line several years ago. The insert on the right is from my (non-pro, color forms) steel blue, just to illustrate that it's not a common insert. Note that there are no pro pigments listed on the precautions listed. Bright fuchsia isn't eye safe and nor are most of the darker mattes so...where are they?!
