I have seen some old accounts who have left writing because of some other users who gradually Downvoted them, @taskmaster4450 is one of them. I have seen his last blogs on which he got Downvotes, & we all know he was too much of active and daily publish his thoughts on chain (he still is active but just on InLeo), the other is @freecompliments he was running his own community and people was getting HSBI from the post within the community, but he received too many downvotes by that he left Hive. The third on is @introvert-dime , he almost had 200k Hive power but was forced to leave Hive just because some people downvoted him...

There might be a reason of down-voting, but these were not just authors, they also used to help new comers to be motivated over here...
