Not for the tons of legitimate reasons, but for the fact that opening any page on there causes my browser to jump around for 2 full minutes while it loads and reloads ads and other crap. Don't even start if I try it on an iPad - it's basically a game of, "can I stop my finger from clicking the thing I want to click before the page moves around and it turns into an ad?"
What is more annoying is that I have ad blocker loaded when I use my PC, but even if I don't see most of the ads, they are still doing this. What year is this?! Get your shit together.
