Media coverage of such incidents further amplifies fear and discourages potential users. In response, platforms have increasingly emphasized proximity-control features that allow users to protect themselves both preventively and reactively – most prominently through safety bubbles and avatar blocking. However, no study to date has examined whether these features influence adoption-relevant factors. To address this gap, we conducted a video vignette-based online survey with 195 participants in Germany, each exposed to a mild personal space invasion scenario under one of three conditions: no safety features, safety bubble, or avatar blocking. Results show that both safety bubbles and avatar blocking positively influence relevant adoption factors such as trust, controllability, satisfaction, and use intention. Safety bubbles additionally improved perceived safety and reliability, appearing to be the more effective solution due to their preventive nature. Finally, implications of the findings are discussed.engSocial Virtual Reality (VR)Metaverseproxemicsvirtual territorybullyingtoxic behaviorinteraction consentprivacy controlmoderation toolsmute004conferenceobject10.1109/VR67842.2026.00062
