Its interesting to know that RP is lowered in case of self upvoting. However I was not really concerned even when I noticed trending authors upvoting themselves and I don't think lowering of RP works effeciently in the case of post which gets lots of votes. Hope you have cleared that in your upcoming post. Further I was really concerned when I saw the user voting his/her own comment and not voting your post even if he/she has praised your post in the comment.

You will see in the next post how they ended up losing RP for upvoting them selves :) its not directly correlated but indirectly. Yes it is sad some never upvote the post, I always end up on the top of the list of most undervalued posts :(.
