I actually cracked the karma code. I increased my karma by 12-1500 in a day and a half. If you see me, you will see I don't have much karma after two years. The key is to go to Top/rising and select the past hour. Pick ten posts to make a comment on. I usually pick the ones I like and the posts that have less than 10-15 comments. Do that every hour for 5-6 hours. Not every comment is going to get a bunch of likes and you will have someone argue with you, dislike you, ECT. But I did this about a week ago when I was at 2800 karma or something like that. Try it out! It was fun but I don't care too much about karma, so once I cracked the code the chase was done. Good luck karma sluts!
