NEVER get the assumption that up/downvotes mean anything on reddit. So many false stories gives thousands of upvote. If you correct someone in comments, karmaroulette starts spinning. Either they hate you or love you. And if the first vote you receive is a downvote, you are already doomed to lose maybe 10, maybe 100 karma and stay hidden at the bottom of the comments.
The whole voting/karma bullshit makes so many people just adopt the karma-generating hivemind. People get rewarded by a virtual number and more visibility for the comments and it fucking works. (Hypothetically:) Combine it with bans for wrongthinkers and this platform could be(or is it?) a great tool for massive manipulation.
I would love a reddit without karma. /rantover
tldr: don‘t give a fuck
