Everyone can do whatever they want with their stones, sometimes F2P players do get lucky, and I'm sure that there are many F2P players that managed to pull LR Goku Black, or maybe even another LR. But for the majority of people, it's a complete waste of stones, which means no LRs, and perhaps no INT Gogeta or SSJ4 Goku (whose rates are much better, meaning that those stones would have been much more useful).

I've seen people pull LR Goku Black with just 150 stones, while others pulled him with 1700 stones. So in the end anything is possible, the only real question is: "is it worth the risk?"
