My wedding

Does the Rabbi mean that they are not careful about this? And if so, in the case where the person “exposed himself” not well. He broke out and so on’, in a way that clearly when he joined the program he did not expect to “humiliate” himself in this way, is it forbidden to talk about it (which his consent was a reference), or does the mere publication of the event remove it from being a slander?
And since the mere publication of the event removes it from being a slander, is it permissible to analyze and interpret the event from a unique perspective (for example, a psychiatrist who diagnoses something professionally)?

Sorry for the “trouble”.
Thank you very much!!

This is beyond what they forgave or gave up. This is known and done in my millionaire's mouth, so I don't see anything in relation to this as a prohibition. This doesn't mean it's appropriate to talk about it, but in my opinion there is no prohibition.
I didn't understand the last question. Analyze what you want.

The question is, am I allowed to professionally analyze body language or whatever it is, and publish it on my YouTube channel?

This is a question of the ethics of treatment, not of Halacha.
