Not sure if we're on the same page but I was kinda curious regarding the hesitancy as well.
If you're a person with any sort of fame, whether or not people know your internet moniker doesn't change the fact that you still exist. Anyone who would want to hack into someone's personal info would do so because they suspect that person is wealthy, not because they know that person frequents a message board. If you'll go as far as saying you're relatively famous and well off, you've already let the cat out of the bag.
I do understand the hesitancy from the aspect of not wanting to have people just give him crap over how he has played. Totally reasonable to be cautious cause the net is full of people who would harass him just because the attention they get from a celebrity or semi-celebrity makes them feel good.
