I know we're no longer permitted to talk about this in a particular thread so maybe I can ask here.

How do the moderators of this site deal with users if they visit the site through a vpn / proxy / mobile data?

For example, I'm visiting this site right now on my phone, the phone is connected to my home wifi. If I turn the wifi off on the phone it uses mobile data 3G/4G etc... Both ways give different ip.

It's just as simple on a desktop / laptop where I can access a wide range of ip addresses.

Does the site have any way of dealing with this?
