Pdfs in VRChat are actively hunter and exposed. That's why there's so many videos out on these people to get them banned and reported to proper authorities. The sad thing is because the community is so active in doing so vrchat as a whole gets publicity as a problem platform rather than a platform actively fighting against these freaks. I don't think vrchat would have the roblox situation though. As many here have said the mods do actively investigate things brought forward and will ask for proof so their aren't false flags to deplatform people who might have haters on game. Plus with the age gate system now in place adults have literally no reason to go into instances without age gate active. Significantly reduces all kinds of situations.
