I don't think the Grinch Leak so much as fooled everyone because of how legit it looked but more because everyone wanted it to be true. There were many reasons not to believe the leak, yet people disregarded those issues because if the leak were real, we'd be getting everything we always wanted.I don't believe any leaks at this point tbh after Grinch leak. When Grinch came out it convinced almost EVERYONE, including me somewhat even though I still wasn't completely sure (70/30 towards real). And then P L A N T happened which ****ed with leaks even more. At this point I don't trust anyone
Either way, you're right. It's best to be skeptical when it comes to leaks.
But if you decide to believe anyone, Verge's Smash leaks have been on point since e3. He even called Piranha Plant (or atleast an additional character being added) before the direct even aired.
