I see a lot of sites (including those behind Cloudflare) being blocked when using Cloudfare's Warp VPN. 403s, captchas, etc.
It would be nice if Cloudflare could put abuse control measures on the front-side, and stop the abuse before allowing it to exit their VPN. E.g., if Cloudflare detects abuse with their existing anti-DDoS, anti-scraping, etc. measures, and the client is on Warp, instead of creating a poor experience for every other Warp user sharing that exit IP, just block/aggressively throttle the bad actor's traffic at the VPN terminator.
They have struggled with credential stuffing, captchas were the only way to stop our login pages from being bombarded at one time. They are getting better with it though but I would rather not lose a tool of last resort.
