Don't take it to heart. I think all this happened because of few Steem accounts upvoting your content. The idea was to neutralize their share which was not a bright idea.

Anyway, if you haven't noticed, few Steem accounts are here to farm Hive while there are few Hive accounts which go to Steemit to farm Steem. Both try to down vote the other. You just got caught in the cross-fires.
