i believe that it is normal for a person that write a post to upvote him or her self, which mean it is right.
for you to write a post or to comment is a good one,once you know or sure of what you have written that you will surely be given a vote,you can also vote yourself which is normal,we all know that to type is not easy not to talk of to think of what to say or type,but it is only over doing that is not right.
what i mean by over doing is voting yourself Every time, is not right
