  The ethical design of social Virtual Reality (VR) is not a new topic, but
"safety" concerns of using social VR are escalated to a different level given
the heat of the Metaverse. For example, it was reported that nearly half of the
female-identifying VR participants have had at least one instance of virtual
sexual harassment. Feeling safe is a basic human right - in any place,
regardless in real or virtual spaces. In this paper, we are seeking to
understand the discrepancy between user concerns and designs in protecting user
safety in social VR applications. We study safety concerns on social VR
experience first by analyzing Twitter posts and then synthesize practices on
safety protection adopted by four mainstream social VR platforms. We argue that
future research and platforms should explore the design of social VR with
boundary-awareness.
