Steem

I don’t understand why sometimes my votes give points to posts and sometimes it doesn’t. I also don’t understand why if I vote too much the system stops me from voting OR my votes no longer give out points!!!!! Who created such complecated system? .... but worst of all Why? WHYYYYYY I cannot post again for 5 minutes? .... when I am in it for 10 minutes I can only do to posts which just makes me want to leave..... this is so stupid
