Do yourself a favor and don't use cloudflare: https://expatcircle.com/cms/why-you-should-never-use-cloudfl...

I am currently thinking about signing up to https://politepol.com/en/prices It can circumvent the Cloudflare blockage of some blogs where I want to subscribe to the RSS feed. Clownflare is the cancer of the internet.

Worse, even if you don't use it, some wordpress plug-ins seem to use it. You can see if you use the no-script extension. I just threw out a plug-in that I found always suspicious. I think it may have been one cause why my pictures did not index well on google. It seemed to use alicdn without even bother to mention this. WTF?
