Back in the days people thought it would be cool to post duplicate content on various sites just to pimp the ranking. It's a bad thing. Google is really bitchy about it.
It's even more terrible because steemians don't have a clue that they potentially produce duplicate content when they use different apps. Serious Problem.
Thanks to all the developers here who work hard to make steem better and better! It's great that you work on a solution. Cheers.
