I know HN prefers not to discuss site misbehavior, but since there is already is a thread...

This site had it all. I think I had something like 4 or 5 overlaying popups/infocards, plus ads. When I tried to scroll it redirected me to the next page, and then it hijacked the back button on top of that.

Revisited to count the garbage: Donation beg, cookies, sticky ad on the bottom, "Add to home screen", "install our app", notification bell button. White space in the content area, with an ad underneath. No content visible at all.
