I think it's inevitable things like these happen on every platform that enables mass social interaction. On fb and twitter etc, our reward system is triggered by likes and retweets, on steemit, it's triggered by big upvotes. It's a flaw in our psychology but a platform like steemit is only better because it doesn't harvest our data and sell for money. Every social platform even the Internet generally demand our attention and can eventually become addictive but the question is do we have enough presence of mind to not get carried away and also do we get remuneration for our attention? This is why I am only active on steemit since I found it, if I'm going to spend my time, at least, I will get paid for it.
