Accessibility and web filtering

[okg]

There is another kind of accessibility sign. Users are often use ad blockers and so on.
These utilities might include their own principles of operation (or bugs) inside. As a result, your site visitor might not see the supposed content.
Does anybody think about it?

Also have a look at a page I build with a pop-up windows, which functions even if the user have disabled JavaScript in his browser:
