Collusion means cooperation and mostly in unwanted activities. Businesses collude to keep prices high. Like in Pakistan, Toyota, Suzuki and Honda collude and bribe politicians and authorities to prevent entry of any competitors in the market (Nissan, Renault etc).

Collusion on Steemit too is for unwanted purposes. Mutual voting by whales deprives community of flourishing and depletes reward pool at an unprecedented level.

We need more people who are acting as investigative journalists, sort of, like @littleboy. You, @transisto, go one step further and downvote people who are harming the ecosystem. We need to report this type of users, so that they lose all their following and responsible people handle their collusive practices with might of Steem Power.

More power to you!
