Can I add sites that try and take over my scrolling ability so it's nice and "smooth" but just ruins my ability to scroll to the target area?
At this point when I run into 90% of this stuff I switch to Reader mode in Safari, which also cures things like insane font sizes and pages that refuse to let you zoom in.
Reader mode not available for your site? I won't read it. If you want to go out of your way to make it hard to read (not just ads that distract, but ones that cover up or things like scrolling that break basic interaction) then you must not want me reading your content.
