I was going to make a comment about using netcat to send files, and Cloudflare blocks the submission. I have never seen this happen to me on HN.

Has anyone run into this before?

Any code including netcat (for it's tendency to be used in reverse shells) or SQL (for it's tendency to be used in SQL injections) tends to be blocked across the entire cloudflare-net these days.

Interesting. That's the first time I have run across this. Makes sense.

That does not make sense at all; it is batshit-crazy broken.

Cloudflare has access to everyone's cleartext? I was unaware of this. NSA must love that

Huh. Just tried submitting the same comment with the same result.

Minimal test, if I try to edit this post removing the asterisk, I get the "banned" page
