Eh, if you put it on a router, how would they know? Was going to set up wg to route to one IP to allow multiple households - but after the witcher fiasco I thought ‘fuck it’ and unsubscribed.

I would imagine that they are looking for IP addresses of known VPNs.

What they do is they monitor the ownership of blocks of ip addresses they call it autonomous systems numbers or ASN’s it’s basically the way that farms of servers claim ownership of ip addresses
