Brother you have explained very well about all the questions which were mentioned and its good to know from you about the main difference between working and curating which is responsible for increasing the popularity of a post and for the increase in Curation reward respectively.

Further more you explain in a very good way about the prohibition of the action of self voting which is very common hair and mostly in new users who don't know that self what is good or not so it's good learning example for others and everyone and learn from it that why self vote is not good.

At last I just wish you good luck
