VPNs are commonly used by all kinds of people for mundane things. any kind of darknet kind of stuff is often associated with illegal activity and will be seen as suspicious by your internet provider
again, it can’t just be any VPN, Proton, Mullvad, Nym…and maybe iVPN if you don’t care about the number of locations you can connect through.
you also want to have a few other things open. Anything that makes additional noise in the connection. Even if you use Mullvad’s Daita feature, it’s good to have some extra noise being made while darknet-stuff is being used
oh…I skipped over the primary purpose. If they give you the third degree about using a VPN just say that you use it to keep yourself safe from crazy people online. You can’t play that plausible deniability card with things like snowflake and Tor, but you can with a VPN that’s available to average consumers

But if you use a VPN regularly, like always, suddenly seeing a different type of traffic would look weird
