https://steemit.com/abuse/@tarazkp/downvoting-is-sweetsss

This one has been operating for over a year or so on the same users, almost 0 comments from the accounts, no interaction, only powerdowns and selloffs, there are many still doing similar things but we figured we'd start with one of the biggest and most obvious one for now.

The example linked above is a good way to identify them! Everyone has some favorite authors that we vote frequently and there's nothing wrong with that :)

Yeah, the Sweetsssj case acid gave is a good example: pure circle jerk with little effort content that gains no outside interest or engagement, treating Steem as a cashcow for free money, nothing else. You definitely aren't part of something like that, I'm sure :)
