I haven’t set up this yet, but I use AdGuard on my phone and yes, it does leave blank space. Sometimes I don’t realized there was more text to read because it’s empty.
It’s not about the adblocker though. It’s on the quality of the developer. A good developer tells the browser to leave space for ads before it loads them. It makes the page load faster and also prevents the page jumping around as each item loads.
Ironically, a bad developer that doesn’t do that, probably has better website layouts for people who use adblockers. 🙃
Don’t you love scrolling right when the page loads and you click an ad instead?
It’s a feature, not a bug! Haha!
