You said that the source was 100% verifiable and not only that but it has also been verified. I am simply asking you, the person making the claim, how and by whom it's been verified.
There are ways to reason on things even if you don't have all the evidence.
Consider if it was faked. The person faking it can't just hope that someone one day stumbles on it, it could never be found. They would either have to release it themselves OR tell someone else to go check it out.
So it comes down to whether the person saying "I came across this when *I* registered on a dating site" is telling the truth or not. I have no reason to believe or disbelieve them, but I doubt the scenario that "someone made it up and just hoped someone else would find it and then someone did happen to find it" to be realistic.
But knowing what I do of Lloyd Evans, the fact that he's once again left his wife and children to go holiday alone, and appears to have been trying to contact women for meetups, does totally match his behavior of the last 4-5 years (that he's recently admitted to, longer for his sexual indiscretions and cheating).
Of course, it could have been made up and the person reporting it is part of the fraud, but if people vouch for them, what would they have to gain vs what would they have to lose? There is no reason to do it.
I certainly wouldn't trade my reputation just to take a cheap shot at Lloyd, however dislikable he is. But if I came across something that would be embarrassing to him with no reason to doubt it's validity I would tell everyone about it.
So that is what I believe the situation is. If people I trust are saying "I trust this person" then I think it's real. Other things (like Marko) also seem to match his MO but have more question marks over them because of how they were revealed and to who.
Dijana said she has no such relative. Mark O'Donnell also said "Marko" is not a relative.
I don't believe what either say, for different reasons. I don't know if it's really Dijana saying anything or being coerced to say something. I don't see how Mark O'Donnell would be any expert on Dijana's family tree and think when he said that he was pretty much in bed with Lloyd which makes his opinion about Lloyd less credible and it more likely to be something he's repeating from Lloyd. So the claim may as well be "Lloyd said ..." in both cases.
