I think the whole grooming/CSA allegations are a pointless rabbit hole to go down right now. Even if you could prove the emails are real (as in an actual email) it doesn't mean anything. You need a witness to the crime. Even if Dijana said that lloyd admitted such or some other person made this claim you would still need the victim. If it is real it's likely to be a dead end until the actual victim comes out.
I have some suspicions about all this anyways. One big flag for me was how Mark O'Donnel's statement was written and how Leah Remini handled the allegations. It was as if they had seen hard evidence that the allegations weren't real. This would make sense if the allegations were fabricated and Lloyd could prove they were.
Call it a conspiracy or whatever but I think either Lloyd or someone close to Lloyd wanted to prove how his "haters" would take anything and run with it. So they "leaked" this story and then shared what they did with Lloyd. He realized most wouldn't believe it since no victim existed and it died on its own. What that scammer went after Mark, Cora, Mikey and Kim that sealed it for me.
Why wouldn't Lloyd publicly come out with the info? If his fingerprints are actually on it that could hurt him. So keeping it lowkey works better. It makes his "haters" look like frothers. The more exposure the evidence its fake gets the closer it could tie Lloyd to it so he could have a reason to keep it in a tight group.
If it is real no one will know until the victim comes out of the woodwork and likely only the police will be ever to track that victim down.
