Hello @crypto.piotr
First of all, before I get anywhere, I just want to know if my upvote registers in this post because I had a message before that says I upvoted them and then, it did not register in their posts. so just let me know if my upvote registered or not because, I am honestly voting posts and not just randomly selecting people or post to upvote. I read them.
You are right. In our community, its very sad to know that the more SP you have, the more power you get so us, poor teeny tiny things are just fodders when it comes to fights with bigger steemian fish.
Yes. you can deliberately destroy someone's reputation by downvoting them but, if your posts is just as decent and good, there's no reason for anyone to do so even if that persons holds a grudge on you. others will see your posts and upvote it again if they like it. so the key is to create quality content.
I feel safer using steemit compared to any other social networking sites because what you say gets recorded on blockchain and, its forever. Which means to say that you better be in your best behavior when it comes to posting because, who knows? Probably the next person who reads them might be your boss or your worst enemy! So, before posting, think twice of its impact in your future life!
You know what's great with steemit? I do not get spammed by my friends who obviously needed to post their selfies, food trips and whatnots. Yeah, I know that half of the people who "likes" them might not really believe that their lives are awesome but, that's life. You are your own pr man so , I guess, everyone for their own selves.
