I Got Worried Voting

What an observation yesterday while I was giving some upvotes on the posts that I find interesting and helpful. I thought it was a glitch but I tried one more time. The possible earning of one post had decreased in value right after I hit upvote on it. What? that made me feel bad and guilty I caused that I thought so. Did you experience the same thing my friends?

This is just a quick post today but I found one trick if I may call it so. No I do not think it was a trick. Well, if you type as a comment on your post "@onepagex" you will automatically get one upvote from that account. Go try it for yourself.
