Not my experience at all. We've reported hundreds if not thousands of sites and with few exceptions they have taken them down swiftly. Definitely one of the best cloud operators when it comes to this.
As recently as August 8th, I reported a phishing site targeting seniors into installing a pre-configured Atera client (who _also_ failed to respond in a reasonable time) by pretending to be an event invite. It was blatant and obvious phishing. This was the response:
---

This is the typical response for me from Cloudflare - it took 2 more weeks before it was finally taken down. If I had to hazard a guess, your high volume of reports gets you into a very different support bucket than the occasional reporter.
My most recent experience was terrible for two reasons:
1. They didn't take down an obvious banking scam site that was hiding behind their service
2. They forwarded my "report phishing content" submission, including contact information, to the scammer, resulting in a roughly 100x increase in the amount of spam I receive and ensuring that I won't ever use their reporting function again
