This is apparently a cyberbullying thing, not a libel thing. So after reading the French harassment laws, it doesn't matter if you said something entirely true or not. It just matters if the harassment is repeated and caused a decline in health and that you did it more than once. So Khelif doesn't need to prove anything, other than mean tweets made her sad.

On another note, I'm shocked that France has a law that says if you post more than one mean tweet about a politician you can go to prison for 3 years.
