For me, it doesn't break anything with their filters. Using it on both phone and PC and I don't manage to hit the free limit for the month. (unless I forget to close the GOG launcher, which for some reason is pinging all the time and blows through the monthly usage limit in a week)

Mullvad, however, leads to Captcha City and is straight up blocked on a couple of sites, namely McGearHub and, for a time, Runescape. Btw, if you have a friend using it, you can likely mooch off their sub. I share mine with 2 other people since the device limit is 5, and I only have my phone and PC on it.

I'm guessing the captcha city situation might be better with more "casual" VPNs but I doubt it makes much of a difference once you have a bunch of people on the same IP.
