Yes, it is! With just a simple dot!
It all began with a Reddit thread , in which visitors spoke about a strange bug in The New York Times paywall:
Bypass the New York Times article paywall WITHOUT addons by adding a period (.) after ".com" and before the slash (/)
Well, few weeks later, participants in the discussion discovers that this "bug" affects a lot of sites with ads, including YouTube videos.
This is a hilarious bug. Every domain name ends in a dot, but it's hidden by default on almost everything. The browser only makes a request for everything after the slash. What must be happening is a client-side script is comparing the url in the browser to a list of paywalled pages and because it's not an exact match, it just lets it though
The problem will probably be corrected soon but, in the meantime, enjoy an ads-free web!
