That type of action (not yours) makes me really angry. I saw the down vote brigade hitting posts with nothing wrong with them this weekend other than they were high in the trending list. I also saw people referring to steemit as a Ponzi scheme.
I had enough and thought I needed to post something. It didn't get MUCH traction, but I still think it is relevant and it is my attempt to stop the same thing you were attempting to stop.
I am making a list of my own of people I see down voting posts that don't have anything unavoidably offensive, not plagiarizing other steemit users, etc.
Looking for patterns. I AM starting to see some.
EDIT: Also, I have noticed the weekend LACKS activity from of the high steem powered people. Often their votes negate these people improperly flagging posts. As my list is showing almost all of them are pretty low in the steem power. Lower than me, and my vote doesn't generally do much. So it only takes one vote from someone with good steem power to negate their effect. Sadly, the weekends are nowhere near as active with high steem powered people as during the week. Sunday's are particularly low.
