There's still cool stuff there and unique and positive interactions to be had, but it's a slog.
"Second Life Is Plagued by Security Flaws, Ex-Employee Says; A former infosec director at Linden Lab alleges the company mishandled user data and turned a blind eye to simulated sex acts involving children."

This community is now deeply imbedded in VRChat, another platform full of unsupervised children and security flaws.
In this case, an exploitable platform filled with children and near-zero moderation of sexualized content. As you know, VRChat doesn't even have an NSFW tagging system or option for users to filter such content out (without hiding all custom avatars, i.e. disabling VRChat's core functionality).
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.
