No, this is just plain wrong. The hitbox is the same one on all skins. On payed skin like peely for example, the skin is bigger and will be more visible, but the hitbox stay the same. This is pay to loose if anything.
I consider it better than 0 source at all. I also have access to the decrypted assets of the game and can personally confirm but the value of that is nil since I can't bring proof.
I'm pretty sure you could find dozens of sources confirming that too, but I don't have the time atm.
