There's nothing on the site's CoC page that says that VPNs aren't allowed so I'm assuming they are fine.

It's one of those "yes, but..." kinds of things.
Yes, VPNs are allowed to be used. However, a number of VPN IP addresses had been banned over the years due to repeated abuse.
So, your experiences may vary.

@DragonFox69: @Cinder: thanks for the answers honestly these age verification laws are going to be a major asspain but im planning on getting a vpn anyways just didnt wanna get banned for using one
