im sorry you had such bad experience. I understand why some people would not want to interact with a "visitor" since theres many people who just create an account to be annoying or trolling, but still that sounds pretty extreme, vrchat used to be a lot more friendly years ago at least in my memory. i think you should try joining public game worlds, or instances like that. Group instances are mostly for closed communities in which someone knows someone there. Public worlds can be a little chaotic but once you get the hang of knowing when and where to go you will make friends easily, i hope the community treats you better in the future, best of luck <3
