Well! I am not a tech guy. I am just a tech enthusiast and an end user of Apple products. I am a doctor but I do like to play with software, hardware and networking stuff that I get exposed to.
When I replied to for the first time, as above, I'd suggested you guys to use safari extensions to detect whether any website is a problematic one or not. After that (or maybe even before that reply), I personally have encountered cloudflare.com for many times. I think until now, I didn't realize what you guys were actually wanted to ask, in regards to cloudflare.com.
Before today, this thing didn't flash in my mind because of the following 2 reasons.
1. Even though, I've encountered cloudflare.com for at least 20/30 times in the past 2 months, I've never seen it as a problem (as you guys did). The reason behind me encountering that site (asking me to verify if I was human through a captcha) was too obvious to me after my 1st or 2nd encounter with cloudflare. Why? ... I am going to explain that below.
2. The cloudflare.com link that somebody have posted above, leads to the homepage of the cloudflare.com. And it is not the same page that we encounter while going to some other websites, e.g. athriftymrs.com link posted by @mh2khin above.
These 2 mistakes above, kept me away from understanding you guys' real concern.
SOLUTION to your problem (I've discovered this though my own encounters and don't know if this is posted elsewhere).
This website is not a threat to your security. It is not a malicious software or a survey loop or a website that wants to sell you something.
Actually, the website sees you guys as threat to the security and services of its own and its clients. And that's the reason behind cloudflare.com asking you to enter captcha solution to confirm that you are a human and not a bot.
Just google cloudflare.com and you will know what it is and what services it provides.
I really don't know the proper tech terms but, what I've understood by myself from the first/second encounter with the website is that coludflare.com is a web hosting service. It is a cloud based server or something of that sort. So, when you want to visit a website that is hosted on cloudflare.com servers, it is cloudflar.com's responsibility to protect the data and service of cloudflare and its clients. Also, by asking the captcha thingy, cloudflare.com security is trying to avoid automated traffic attack though bots.
Ok, now I understood that the website is just trying to protect itself.
But, BIG QUESTION: WHY ME ? (in you guys' cases ME = you😉)???
Well, I have a sure-hot answer for "WHY ME" (ME= TimbukTrue)? And most likely, it is also the case when ME= mh2khin or dipakcg, etc.
It is because I was experimenting with VPNs or Proxy server bypasses or a TOR Browser, when I encountered the problem.
As I've tried to explain above, the cloudflare.com is a web hosting service. It is trying to protect itself and its clients.
Even though, VPN / Proxy server / TOR are highly secure services that protect my identity, their exit IPs are limited in numbers. While the number of subscribers they carry could be any number. It is most certain that the IP address that cloudflare.com getting signals from (via VPN/Proxy/TOR) is used by thousands of people around the world everyday. Thus, cloudflare.com's safety mechanism sees it as a threat and wants you to prove yourself as an alive human before letting you in and increasing incoming and outgoing traffic as well as accessing data stored on their servers.
Sorry for this big essay, but, as I've mentioned earlier, I am not a tech guy. So, I couldn't keep it short and sweet.
Anyways.
I can say for sure that cloudflare.com is safe and good website. In my above post, I have mentioned a safari extension named 'WOT' (Web Of Trust). I have attached a picture of WOT rating of cloudflare.com to support my belief that cloudflare.com is safe to visit.
Check the reputation of cloudflare.com at https://www.mywot.com/en/scorecard/cloudflare.com
If you still don't want to see cloudflare.com on your way to your desired website, try to go thru a unique end user IP (e.g. home broadband connection) and not through a professional bypass service (e.g. VPN, Proxy, TOR etc.).
I hope this helps you guys.
