Whats the harm in asking Bazza if he knew Epstein or not?
None. Feel free to ask him.
As to why IFL etc might not want to ask, it might not be a good idea to insinuate that the father of one of the most influential men in boxing is a paedo unless you have some evidence. It's bad for business.
Knowing a paedophile isn't evidence enough that you are one. Any of us could know a paedo and not realise it.
Loads of people have my details and I'm an average guy. Imagine how many legitimate contacts someone like Epstein or Hearn will have.
Therefore there are plenty of legitimate reasons that epstein has his details. He probably used him to get tickets for stuff when he was entertaining.
Prince Andrew was different. There have always been rumours about him, he has been accused by one of the victims, photographed with that victim, and he's a public servant. He had to be asked about it
