Yes, you are right. I assumed that they wouldn't possibly photoshop out her mole on every single image... which I was wrong. I've collected a few of her pics, and among those I've counted at least 171 pictures where her mole was visibly removed: http://imgur.com/a/2t7x0cp
There were, however, three pics where it was left intact:
The last pic doesn't show the mole on her arm, to be precise, but it shows other moles - one under her right boob and another on her right thumb (which you can see she also has on these two pics):
And just noticed that you can also see a mole on her left boob on all four pics
One user had posted one of the pics providing her Instagram as a source: http://www.reddit.com/r/CindyPrado/comments/a2rndu/, but it's been since removed, so it's difficult to verify
