You do not see a problem in voting people up and down?
It is personal, instead of work focused.
Can you name an example where you can upvote and downvote people on a content platform. Or even a social media platform? Directly, not by indirect means of followers or lack thereof.
There is reasons why you will be hard pressed to find an example. In short, it is a bad idea.
I could not find any examples. But I did not search extensively. Maybe you will find an example where it was possible but was deprecated.
