Honestly, I love the Trust System and all personally but, it's not perfect. Today I just witnessed some person crash one of my friends over some petty drama without even using a particle system/shader(I made a report already of course.)
That being said, would it be possible to implement a two-step verification? I know the downsides and criticisms such method would receive however-- the fact that crashers are still a problem would justify implementing this.
This method although not a permanent solution, would help alleviate the issues of crashers and so forth that evade IP bans and such.
To add on;
A game called Tom Clancy's Rainbow Six Siege implements this feature requiring 2-step verification in order to play ranked matches. This method is used to "flush" out toxic players from the game. I understand VRChat isn't a shooter game however, it could really help.
