I could do - but I'm kind of angry that I even have to. What about the less technically literate, who might barely know what CloudFlare is, let alone figure out how to contact their support? (Yes, I use a VPN, but there's plenty of ways a non tech person might have a shared IP.) And why should I have to go to this effort, just to get read access to a website?
And what if I'm on a different IP tomorrow? Begging for my IP to be unblocked is no long term solution. (What about when malicious activity comes from it tomorrow, after you unblocked it? You'll just block it again.)
Just now, in my other browser tab:
