Just tried using Firefox Quantum 62.2.2 on Debian with different configurations - NoScript enabled and disabled, and tracking protection enabled and disabled. Can't seem to replicate what you're getting.

What browser and OS are you using? Do you have any plugins/extensions active? (Ad blockers, etc. I don't run any, NoScript does a better job.)

Seems to happen in Chrome for Mac and Android. No extensions or plugins.

Gotcha. Turns out to be Chrome (or Chromium) specific.

In article.js loaded with this page there is a section that looks like:

dataLayer.push({event:"mittr:detectIncognitoMode",action:"detect",category:"incognito-mode",label:n})

Commenting out the function block surrounding it where it starts with "function y() {..." stops the class ".incognito-wall-shown" from being applied to "section.incognito-wall" found in the main HTML page - although this is just a quick dig and haven't debugged any further (I'm halfway through something else but this caught my interest ;) )
