Even on a karma platform, I didn’t care. I always used to make fun of people on reddit for deleting a post just because it was heavily downvoted. But then… eventually it wasn’t enough for people to dogpile downvotes, they had to start reporting posts they disagreed with. And the mod teams, who had eventually also gone to shit, didn’t delete the posts but instead would ban you from the sub. At that point, deleting your own post because of downvotes seemed entirely reasonable and I even started doing it myself.
