Papageno never really says he doesnt believe them... He's always like either on the fence or says there's credibility to it. Only time I saw him say he didnt believe a leak was when he covered like random image leaks... Like sassy geno... But even then he wanted to believe.Except he doesn't get behind every one? Have you watched any of his videos?
He also mainly makes videos on the "more credible" leaks. If you want gullible go check out LaxChris.
