Every vote on a story does not give you karma. Its maybe 50%, and I think there are more complex rules, e.g. if someone usually upvotes your stories it doesn't count (I don't know this definitely, it's a theory explaining some observations).<p>For comments, I've never seen anything but a 1:1 relationship i.e. comment points - 1 = delta_karma. Sometime there are delays though, and sometimes when people upvote it doesn't change the comment score.
Yeah, your account is hellbanned. I can't see the things you post, your profile, all of that ;-)<p>My impression lately is that some caching might be going on and that the karma count seems to sometimes lag behind votes.
