+## X-adblock
+
+Script to automatically block accounts posting ads on x.com. [Ublock Origin](https://addons.mozilla.org/en-US/firefox/addon/ublock-origin/) is a much better option. But this script was written thinking "If I block every single account posting ads would I stop seeing ads on twitter? How much time would it take?", still unanswered for now.
