Seriously? On the spectrum of things worth ad blocking, this would never even hit my radar.
I don't block user comments on PHP doc pages out of spite, I do it because they are very long, making it harder to scroll vertically on the actual documentation.
Its a minor quibble on desktop, but on mobile its a really annoying feature because I have to manually scroll with my finger for an age.
Yes, but then if I'm looking for a specific part it has scrolled way past and I need to then scroll back down, sometimes past it, and then scroll back up. Bearing in mind I have to scan the page as it flashes past too.
It's a frustrating experience.
