From a discord announcement post:

Hello VRChat!

We've just released a new blog post! In it, we talk about our brand new Community Guidelines and Creator Guidelines.

The Community Guidelines have been completely updated. Instead of summarizing them here, we strongly suggest that you read through them. They’ve been completely rewritten from the ground up, so it’d be hard to summarize them anyway!

Additionally, we’ve created a new set of guidelines specifically for creators – aptly titled the Creator Guidelines.

Generally speaking, none of these guidelines are new or a surprise. These new guidelines do not come with a change to how we’re enforcing our rules, but it does mean that our guidelines are much more clear!

Keep an eye out for the Dev Update thread going live tomorrow, where we'll have a section discussing why we decided to refresh these guidelines (the old ones were old. like really old. like someone wrote them before i worked here dude), and will answer questions regarding them.

Thank you!
