It’s getting ridiculous. There’s one youtuber that swapped the thumbnail 4 times this week just to make people look at it again and think it was a different video. The worst part is that it sort of works, I keep looking at it then remembering I saw something very similar from the same channel name yesterday.
I hate this so damn much.
There’s a Youtube extension for community-created thumbnails and titles that overrides this nonsense. Donation highly encouraged but I think you can get it for free.
