If you care fairness, I have 1 extra suggestion that you might be interested in. It was proven by several data-science research that when users have to votes (or give ratings) and if they are able to see the previous result, then the first few votes have an extremely important effect. For instance here is one stury, very well written article by a famous teacher Robert West, "of sheep and beer" https://dlab.epfl.ch/20…
This is not a study but a reality for me. At one point on HN I wanted to farm for karma points. That period lasted for a few weeks, I wasn't too intense about it, just a fun question I had. My tactic? Find something that has something like 15 upvotes and you suspect to be rising quick in upvotes. Create the first comment and your best to make an as thoughtful comment as possible, even if you don't know anything about…
AFAIK points aren't worth anything and don't unlock anything after the first few, probably to help block spam/bots.
It's exceedingly rare that I even click a profile here, and even then it's usually to see what a person works on not how many points they've accumulated.
In fact, there are many cases where the most knowledgeable person on a subject comments, I click to see who they are, and realize they've only ever commented a few times. I imagine they either mostly lurk, or have an idle account they just use when friends drag them into the conversation.
