Apparently some VR environments have the option to prevent close contact of virtual characters in order to avoid this, but children were turning it off because they wanted to high 5 each other. Turning it back on couldn't be done quickly enough if 'attacked'.
This puts the burden onto the victim - so as a child you can't go about the game nicely giving high fives, without being attacked.
The same as the police advising women leave social media, if harassed, the focus is never on making people stop harassing, but always on making victims alter their behaviour.
