People are confusing (probably due to intentional prompting by those trolls trying to have bystanders fight their battles for them) the very real problem on Reddit that if you chase karma there were benefits to be had in terms of credibility and reach of your messaging and so whatever entities might benefit from such would tend to fill the space over in Reddit with content like that. Realistically that doesn’t change the most common content much as it really comes down to the sort of thing people will upvote but it did make it a bit worse. That’s being confused with some notion that somehow anyone who wasn’t chasing karma was entirely ignored. That just isn’t true. You might not be the absolute center of attention unless you’ve either post or said something especially worthwhile but so what?
