It is indeed very disappointing to comment when all your comments get downvoted out of the blue.
@transisto if you really care about new steem users and content discovery, then you should also go after the downvote ring.
And @haejin, you are so well known you could probably just use haejin tag and still make massive profits. You are on everyones lips and mind when it comes to TA and EW in particular.
There is are no such thing as down-voting ring as there are no profit whatsoever to be made by flagging.
Oh yes there absolutely is and it is run by @berniesanders.
Have a look at @gasparcha, he got hit by them several times and went from minnow to nothing but still kept his head up. Wish I had enough SP to help him out.
They may not make profits on such an activity but they demonstrate power. Them upvoting each other make the profits to keep on.
This have been going on for months, and I find it hard to believe you not notice it.
