It seems like there's been a lot more websites that have been deploying anti-adware blocker software in the past few weeks. One that stands out in particular is called Admiral (see websites like GameRant for an example).
I have tried Adguard Plus and Rethink DNS (using the instructions from FMHY), and neither can prevent the popup that stops you from reading the site. I assume there's user scripts out there, but at this point, I don't even know what to search for on Greasyfork.
