Cloudflare is testing my patience.

I there, I use cloudflare for some of my servers. I tried using the cache system but while it works, it also adds more time to the load of the page (TTFB *) so I didn’t worked for me at least in most websites. But, I still use the DNS service which is available to use without cache. So I use mainly for the DNS and only a few pages uses the cache. Nothing wrong here.
(*) CloudFlare says that the TTFB delay is not a big issue. I think the opposite.
However, recently I found the next problems:
- Cloudflare affects somehow the content of some pages even when you are not caching it. How, and why? I don’t know but Google Bots shows me some nonexistent links that were generated by CloudFlare.
- And now, somebody is using the IP of Cloudflare to probe one of my server.

- The IP is owned by CloudFlare https://www.cloudflare.com/ips-v4
- And my website does not use WordPress in any way and there is no file (or folded) with such name. Also, there is no content or link to that file. I double-checked that.
So, what is going on with CloudFlare?

I don’t think CloudFlare is trying to hack my server and maybe somebody is using CloudFlare as some kind of proxy. But, since I don’t really know what is going on, then that IP of CloudFlare was banned from my system.
In any case, I think it is time to move out of CloudFlare.
