Thank you everyone, and thank you, particularly, @gun. One thing I don’t like in today’s internet culture is the ad in everything. For example, everyone that makes a video feel it’s right to say “give a like, subscribe”, taking time of his video and our watching to beg for something that, after all, is not important (and swiping our concentration of the real subject you want to spread to the beg of, what should be secondary, fame or money). So, like when I share a time with someone, I don’t want to waste with photos to show everybody else, when I do something in the internet I want it plain, with me begging for something in my interest or boosting the rating of what I do.

With your answer, I now understand that, if it’s made automatic (like here), should not exist the culture of thinking about it. I may continue not voting (or unvoting) in myself, for the above reasoning, but now at least I understand. Thanks again you and everyone that took the time (and fun) to answer. (:
