Cloudflare captcha

Question

linux

Today, they stopped letting me into many sites, a captcha from Cloudflare pops up. He says that some attacks are coming from my IP and asks to scan my computer for viruses. The problem is that I have all the computers on the network either on Linux or on MacOS and there is clearly nothing to scan.
Here is a screenshot of the page: 199.231.93.124/screenshots/Access%20Restricted.png
How can I get rid of this page?

Answer 1

Option 1: You have registered "left" dns and the captcha is given to you by completely different sites.
Option 2: You did catch a virus, it is quite possible on both Linux and MacOS, especially if you have Java installed

Answer 2

You never know, I went to a web page (for example, the site was hacked), which, under the background of javascript, hammers victim websites with get requests.

Answer 3

Maybe you have an atypical browser user-agent?
Also, Linux does not mean that you are protected from viruses. For example, you may have a malicious cross-platform extension for Firefox or Chrome (Chrome allows you to run extensions even after closing all windows, which is especially convenient) and do dirty deeds.

Answer 4

If we talk specifically about placehold.it, then the problem (or rather, blocking) is on the side of placehold.it and / or CloudFlare, which is why, for example, the Twitter Bootstrap site began to use holder.js instead of this service: github.com/twitter/bootstrap /issues/5722
