Nope. I’d argue that Mullvad is not for most pirates, unless you’re actually worried about being jailed for your piracy (depends on what country you’re in). If you just want to get the letters from your ISP to stop, there are much cheaper VPNs that can do that.
Mullvad is for actual privacy, which many VPNs don’t really give you. If you gave them an email address and credit card, then it ain’t private, kids!
