Thanks for reporting. Here's a link to the offending comments: https://steemit.com/@abusereports/comments
There are literally hundreds in the past couple days alone. All the same, all upvoted by the same 7 or 8 sock accounts to 0.04 USD.
My full downvote is only 0.02 so I can only take down half a comment on my own. Then I would be downvoted to zero as retaliation. Not sure I have enough SP or support to get into this battle.
Agree with you though, those comments are a major problem. I run across them from time to time, and wish the person behind them had never heard of Steem.
