I regularly browse the internet with a (popular commercial) VPN, and the amount of static I get from Cloudflare for just doing that is incredible. DW has actually been one of the worst offenders in that way; its CF protection really doesn't like me expanding comment threads while on VPN. And I know the developer of FanFicFare has had to implement workarounds for fanfiction.net specifically because of their Cloudflare protection.

However, it's better than the one random hardware online store that won't even connect when I'm on my VPN. It doesn't even show a blank or error page, it just continually times out.
