Again... I'm logged in (with 2FA). This should not matter in the slightest.
Your glib reply sounds a lot like: "If you let us trample all over your right to privacy, then you won't get that message."
There are far better methods of preventing spam, or attacks on your server, than blocking my legitimate access, and given that I have 2FA enabled on my account, this isn't about promoting security, either. Even without the VPN, I would still have uBlock Origin to limit my exposure to the malware attack vector that advertising servers have become, so is this a VPN issue at all? Does your site even serve ads? Blocked or not, there would be some evidence of their existence, and I've never seen any. Either you're not serving ads, making the argument moot, or you are, and my protections are working better than I realized.
As an existing customer (7DTD), I'm telling you that I don't like the practice of blocking VPN users. As a potential customer of any future products TFP might offer, I'm telling you that being unable to access support through the website because you are blocking VPN users will weigh heavily on my future purchasing decisions. At issue is whether what your customers are telling you actually means anything to you.
