I am an advocate of everyone has their own stake and can use it as they like. At the same time we have flags, to down vote obvious abuses.
I've been tossing in a flag or two, but it does not do much damage.
Accounts spamming comments and then upvoting:
@transisto - In his defense he did make a post about his intentions and when I flagged him he seemed to be fine with that.
@checkthisout - Most of these have been flagged
Also mostly flagged
Who knows how many others? Plus we have our "Trending Page" battle going on between a couple of whales and a group of trolls that I shall not name. (That way you can apply whichever title you want to either group.
Look guys, I know it's your stake, but it seems short sighted to me.
