Because currently, it seems like the only thing it’s recording are downvotes. Meanwhile upvotes are completely ignored, leading to pretty much every profile I see having a negative reputation.
Also, I have a very fragile ego and my -6 reputation hurts a bit.
For now I use it to save things, since there is no save function.
So it could probably be replaced by that.
But I think it’s also here for compatibility with Mastodon…
