We also monitor the real-time state of total connections per account as we only allow for five connections simultaneously. As we do not save this information, we cannot, for example, tell you how many connections your account had five minutes ago.
I will say, we are trusting all of these providers unless they have a way to verify it. I've yet to find a trustless VPN provider. I don't think it is possible. I'm fine with the tradeoffs of Mullvad and iVPN but I understand why some may not be. But based on what I saw on perfect-privacy I would not trust them any more. I don't like the email address requirement.
