Why are Cloudflare sites asking for Captcha?
I have visited some sites from this forum and it is alerting me this
As I am seeing then sites added Cloudfare and how can I stop cloudflare authentications when visiting these sites?

It is security measure provided by cloudflare to insure that the traffic coming to the site is spam free. It can be always disabled by the site owner.Blogging Tips & Tricks @ Blogwithvk.com

It comes very often with TOR browser and it is not possible to bypass this by confirming that you are not a robot Never worked for me

it happens with TOR browsers once in a while. It's mostly a cloudflare bug, it's happened before but they get it fixed after a few hours. So don't worry about it for now, try a little later and you should be alright, some people get locked out of their own site because of this. Just a downside of TOR

As mentioned by others, it is a security measure in place to ensure that the traffic directed to the website is legitimate traffic. A lot of the time you will see this when either you are behind a proxy or possibly utilizing an ISP in a region that is known for malicious traffic (be it that you might not be causing said malicious traffic). Can be a pain to have to pass through said roadblock, but with today's internet activities it's definitely good to be safe.

This due to your IP is in IP blacklist that site owner blocked and this feature can be found and enabled from Cloudflare.
Here is an article for what Cloudflare said about this.

It happens randomly if the security measure is activated, may be your ip is in a blacklist pool, or simply depending also of your country etc, many things can trigger it, sometimes just refreshing the website too many times in a short period of time.

We use captcha to show that we are not robots.

This happens especially if you are using a VPN service or trying to access a website many time from a single IP. Its a part of cloudfalres security measures to ensure that its human and not a bot attack.
