It’s called the ‘trust system’ for a reason, and it does serve a number of important purposes, one of which is to signal intent. It really doesn’t take long to get from Visitor to New User, but there are probably a thousand times more Visitors than New Users in the system - people who more likely than not never intended to stick around and be a part of the community; people who signed up and logged in just long enough to cause trouble, and either got bored or banned. It takes less than 10 minutes to get a throwaway gmail account and use that to get a throwaway VRChat account; people who’ve been here for any length of time are well aware of that fact, and have dealt with a lot of Visitors who have very much earned their Nuisance rank.
Yes, it takes a heck of a lot longer to get from New User to User, but there are plenty of ways to shorten that time and earn that ‘trust’: expand your friends list, upload avatars and/or worlds, maybe even drop ten bux to try out VRC+ for a month and see if you think it’s worth it (or better yet make friends with someone willing to gift it to you). Putting in that effort and getting up to User rank shows everyone that you want to be part of the community, that you intend to stick around, and that you’re much less likely to be another copy-cat wanna-be troll with a throwaway account who’s only there to make others miserable.
Is it a perfect system? No, of course not. On one hand, I’ve met or known people outside VRChat who wanted to be a part of the community but never made it past Visitor because of the knee-jerk reactions many veteran players have toward Visitors (or worse yet, didn’t even bother joining in the first place because they’d heard about those reactions). I have no doubt there are people with Visitor rank in-game right now who many veteran players would really enjoy befriending and hanging out with, but they’ll miss out on the opportunity because they’re not willing to give a Visitor a chance.
Conversely, some of the nastiest people I’ve run into in-game have been Trusted rank, and I’ve been hit more times by Trusted users with crasher avatars than every other rank combined. It is the internet, after all; you’re going to find plenty of people willing to play the long game for the opportunity to ruin someone else’s day.
At the end of the day, there’s a really easy way to avoid getting hit with Nuisance rank: just don’t be a nuisance. Making friends and finding your niche is absolutely an uphill battle when you’re still Visitor rank, but it’s far from impossible. As the others have said, there are a lot of different people, from a lot of different backgrounds, with a lot of different views; some are far more sensitive than others about particular topics.
The Groups system offers a pretty easy way to gauge whether a given person may share the same opinions and beliefs as you, and if you really intend to stick around and genuinely want to make some like-minded friends, I’d encourage you to seek out and join groups that align with your interests, and to pay attention to the groups the people in any given instance are representing in their name tags (or the owner of the instance itself). To use an extremely silly example, if you join a group public instance run by a vegan group, you’re probably not going to win anyone over by talking about steaks and burgers. (It’s both annoying and amusing how many times I’ve seen people join furry-owned group publics who seem genuinely baffled that there are so many furries running around.)
My cynical side says there’s no way in hell you read all those words, so here’s the short version.
tl;dr: don’t be a jerk, think before you speak, use the Groups system to find people who share your interests and opinions, and if the people in an instance won’t talk to you because you’re Visitor rank, just go to another instance or a different world.
