Show the result of upvotes minus downvotes, you will see a heart icon with the result in comments.

It shows in some comments and posts, but not all.

This marks your account as a bot.

Does this affect how my account is viewed on other frontends or like how my account works? I mean I won’t enable it but I gotta ask now.

I think you can understand the others.

I don’t think I really understand.

I disabled all Show scores, Show upvotes, Show downvotes, Show upvote %, and I don’t think anything really happens. I mean I can still see them all (or some of them), and like now I have all of them enabled but I can’t see who downvoted you, what’s your upvote percentage and your score (although just as I said, this doesn’t happen to all) - I can only see how many upvotes you have.

Also I don’t know what Show read posts means.
