I have been thinking about it but it is tricky from a legal standpoint. What I'm trying to arrange next time I visit is to have a secondary line installed at my parents place that is in my name. So that when I pull heavy traffic from that line it doesn't impact them and I can't get them in trouble for posting a message that isn't government approved.

Heavy traffic to access a bunch of gov websites? There's definitely more to your story then.

I'd say, anything heavy and random, use the general VPN and the rest use an rpi at your parents' home.
