Don't you find interesting that neither my Tor Browser, nor my non-js Firefox had any issues with Cloudflare? I had to force an "all" posts view for Clouflare to kick in.
I do have a significant problem with CloudFlare, which is most likely due to the fact that my opsec is far more sophisticated than you can imagine.
CloudFlare most likely recognized your fingerprint and now allows you to do things that others cannot.
The rest of us, on the other hand, must either find a hcaptcha or a message to enable JavaScript in order to visit bitcointalk.org.
It's possible that you recently solved a hcaptcha that extracted your fingerprint, so when you visit bitcointalk.org, it won't ask you again.
