I use NordVPN for my Internet access (to prevent my ISP from collecting marketing information from my browsing.) But many of the NordVPN nodes are blocked by Hawk Host, which prevents me from accessing my own domain. I can understand that bad actors are using VPNs to hide their activity, and I'm glad that Hawk Host is blocking them. But instead of just throwing a 403 Forbidden error, I would like it to perform a Captcha challenge to prove they are not a BOT. With the current set-up I must randomly try different VPN nodes until I find one that isn't blacklisted. I often have to switch to a node in Canada to not be blocked.
Many sites do exactly this: instead of completely blocking the user completely, they can complete a Captcha challenge, then continue to the site (aetna.com is a good example of that.) The current set-up is frustrating for me, and I have no idea how many users are blocked from access to my site and don't realize why.
I would also ask in advance that, if this is implemented, to please not use the cheesy captcha that is used for signing-up to this forum. It's not only overly tedious, but I had to try from several different browser before I could get past that screen. Google provides some excellent options, some of which base the challenge difficulty on the source IP reputation, and they don't charge for commercial use (I use one on my site.)
