Blocking via an Unsolvable CAPTCHA

I've been on the receiving end of this when using some VPNs -- after a few you realise you're being stonewalled.

It's an _incredibly_ frustrating experience for real users caught in this

I guess they figure "real users" don't use VPNs.

I see this occasionally, but just change servers. And it's typically just temporary. Affected servers are OK in a day or so.

You can’t just green light any known VPN IP ranges though because they’re dynamic, and if you did, bots would just resort to using VPNs to bypass normal IP blocking.
