Interesting article, thanks for posting. The space bubble mentioned seems to work fine and is a mechanism only possible in VR. This is an example showing unwanted touch can be prevented in VR much easier than it can be in real life. The fact your article has been targeted already by shills shows what a real problem trolls and harrassment is in a virtual environment where users are assumed to have higher than average spare income. At least we can simply program things out in VR, whereas that is not possible in real life.
