There are many who do not want to see ads and try to avoid paywalls on the Internet by installing ad blocking programs or other complicated solutions. As it turns out, in many cases, overcoming these "obstacles" is often as simple as adding a dot to a URL.
In other words: Suppose you are not a YouTube Premium subscriber, “youtube.com/gamatovideo” will display ads, but “youtube.com./gamatovideo” will not. It is so simple.
The error is mostly confined to preletterτα περιήγησης επιτραπέζιων υπολογιστών, αλλά σε cell phones, you can use the “desktop site” option to make the trick work.
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 του κεντρικού υπολογιστή, και το περιεχόμενο εξακολουθεί να προβάλλεται, όταν δεν υπάρχει αντιστοίχιση του ονόματος του κεντρικού υπολογιστή στο πρόγραμμα περιήγησης,. Οπότε δεν υπάρχουν cookies και CORS. Πολλοί ιστότοποι χρησιμοποιούν διαφορετικό domain για την προβολή διαφημίσεων με μια λίστα επιτρεπόμενων που δεν περιέχει την επιπλέον τελεία ”
In other words, it's simple blindness and it doesn't just work for YouTube. A quick test showed that it is effective and bypasses paywalls on the pages of 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.
