Lets take the hypothetical situation that Lloyd never actually visited sex workers regularly and never admitted to that, then someone accused them of this very thing.
That's the key thing - no one would have. This is all because he did those things, told other people he'd done those things, and then broadcast a video to tell the whole world he'd done those things.
"those things" being "used prostitutes on a regular basis"
Could there actually be a court case where there is a trail to see if the accusations are true? If the person never saw sex workers what is the actual crime? Defamation? Then what?
It's irrelevant. There is a public confession that he did those things. What he's calling "defamation" is people simply reporting on his own admissions. i.e. it isn't defamatory at all, because it isn't untrue.
If he hadn't regularly visited prostitutes, who would invent such a thing?
If someone makes such an accusation with no basis whatsoever, to damage a persons reputation, then that is defamation and you can sue them into oblivion. But all most normal people would have to do is tell the world that it's a lie, and as long as their reputation isn't that of a dirty grubby little shit, the world knows it would be out of character.
Being of good character is no worthless thing.
