I'm suprised by that because Cloudflare must know the real IPs to forward traffic to for their services to work and I have not read anything that implies that Cloudflare might not have produced that data following a court order of any kind.
I have however seen private trackers and other pirate site use cloudflares services. I am kinda suprised by that since I must assume that pirate site operates would be aware that cloudflare is not actually providing any court proof anonymization or is promising anything like a non-logging/zero knowledge/Anonymization layer like tor or ipfs.
Can anyone enlighten me on that matter?
