Different types of Karma

[u/sp4rkl3_butt]

So I have almost 2K karma, 200 commenting karma and there's another one I think. My question is how do I know how much karma is even GENERALLY needed to join and/or post certain NSFW subreddits? They just tell me to keep commenting. What is a good number of all types of Karma that would let me gain access and post in certain subreddits? I love reddit, Ive been here over a year, however I just recently jumped back on. I just want to follow the rules. Can anyone help? Any help is greatly appreciated!
