A lot of websites want "bot defense" due to high volume scrapers, and that "bot defense" often also ends up blocking low-volume wget/curl and polite crawlers like Common Crawl's CCBot.
Cloudflare can verify certain bots when they come from known ip addresses. So if your site is using cloudflare it can let CCBot if it has done the verification.
cloudflare routinely denies my human-piloted browser now, on many sites.
you're not a bot thats irrelevant
I wonder if you'd have more reliable internet browsing with a browser that was a CF verified bot.
