There are many who do not want to see ads and try to avoid paywalls on the Internetnetwork, by installing ad blockers or other complex solutions. As it turns out, in many cases, overcoming these “barriers” is often as simple as adding a period to a URL.
In other words: Suppose you are not a subscriber YouTube Premium, η address "Youtube.com/gamatovideo" will display ads, but "youtube.com./gamatovideo" will not display. It is so simple.
The error is mainly limited to desktop browsers, but on mobile, you can use the "desktop site" option to get the trick working.
Redditor u / unicorn4sale reported the error to subdreddit r / webdev. According to unicorn4sale:
“It's a commonly forgotten case, sites forget to normalize it name of the central one computer, and the content is still displayed, when there is no match to the hostname in the browser,. So there are no cookies and CORS. Many sites use a different domain to serve ads with a whitelist that does not contain the extra dot ”
In other words, it's a simple negligence and it doesn't just work for YouTube. A quick test has shown that it is effective and surpasses paywalls on The New York Times, Wired, The Washington Post, The Atlantic and many more
Of course, now that the bug has been made public it is only a matter of time before it closes. Enjoy it as long as it lasts.
