Well I think according karma you have enforced commenting limits, so if you comment only ocassionally you won't notice it, but if you wanna engage in discussion and wanna keep discussing then either you have choice of self censorship (not going against HV hivemind) or face posting limits. Other than that if you are under 500 you can't downvote other posts (which is actually good thing and I wish we would remove downvoting for everyone).
