It happens so often where we’re watching a series and as we’re scrolling to the right episode, we see thumbnails made from a clip in that episode. So like if someone was maybe about to die, now I know that’s not gonna be the case. And most of the time, the description says too much.
Edit: I should maybe specific that I’m mainly talking about services like Netflix, Prime, etc.
I’ve had this same thought for years. There’s nothing more frustrating than loading up YT and a recommended video on the home page has a major spoiler in the thumbnail for something I’m interested in. Titles can be bad too, but at least I can skim over most of them and not actually process them.
There’s a way to target elements with ublock origin (element picker tool), so you could theoretically remove all thumbnails.
