Captchas are more annyoing than ads.
(lemm.ee)
A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.
Also the frequency of ads plays a significant role in how hard they are grinding my gears. For example, vanilla YT has become completely unusable because of this. Sites like that are easily above 6/10 IMO.
Those puzzle captchas are a total nightmare. At least 5/10. If they show up in bizarre situations, like the one you mentioned, the amount of annoyance starts at 6/10.
