Seems sensible for anyone with a high profile.
As we live in a world where countless people crave their 15 minutes of social media fame and are happy to claim to be victims of some ...ism or ...phobia a cautious approach is the only sane response.
Recent events have shown that it doesn't take much for a reputation to be destroyed. The fact that in today's world you are not allowed to question motivation or veracity of allegations doesn't help.
Have witnesses and record interactions.
Even with these precautions you need to be prepared for well intended people to leap to the defence of shit stirrers without bothering to investigate facts.
It doesn't just effect Nobel prize winning scientists, there was a recent case in the UK where a minimum wage security guard in a store was accused of assaulting a breast feeding mum, the accuser leaping for social media to attack the store and the guard. It was only video evidence that showed the whole thing was made up and led to her prosecution. People will do this shit without any rational motivation beyond fame so give them a real reason and there are no limits.
