Is there something that can generate random Internet usage to make the real sites I go to a bit obfuscated?
I’m thinking something that runs on my server, and simply visits a random website. It probably shouldn’t actually be random, and some sort of tweaking would be great. Like the ability to have it visit every news site there is. That way the ISP will have a harder time telling my political bias.
The threat model for this is below using a VPN for normal usage, although getting a dedicated VPN IP address is a project for one day.
It helps a lot. Someone would need to go through the effort of tracking your VPN service and correlating that to you.
OP seems to worry about their ISP, and their ISP can’t see anything at the VPN, so they’d need to go out of their way to gather that info. So as long as OP trusts the VPN, they’re probably fine from everyone but state actors and well funded private investigators.
If you want to go beyond that, Tor is your next option. That should be effective against all but the most determined state actors.
