Maybe if people like this comment enough ?
(/s, if you must ask)
There definitely is a type of person that revels in negative karma/points/whatever for their "controversial" "opinions".
But really, I do look at people's karma to see if I should take a comment seriously if I'm feeling uncertain about it. People with 2000+ karma are usually worth listening to, even if you don't agree with them.
I don't see an option in the settings to make that disappear, and adblocking the div removes a useful link.
