human nature unhinged from physical constraints. for some reason despite growing up playing and hacking MMORPGs this never really dawned on me..
What I think happens in places like this is similar to what happens in the crypto world. Money and financial situations can be abused hard, and it has been for a long time, so we have a good amount of rules, laws, international agreements and so on regarding it. Then crypto came, it kinda resembled money, and had none of these restrictions. So every trick is new again: market manipulations, all the different kind of frauds, all unprotected from the existing legal framework that we have for regular money. I think online communications enjoy a similar situation, or at least it did, for quite some time.
The Facebook crowd would be just as bad in VR, probably, but VRChat is its own sort of hive of scum and villainy.
