There are also accounts who manage to stay under the radar whilst making a lot of junk posts. Our 'favourite' market analyst is still self-voting his multiple posts per day with hardly any responses. Other do loads of comments and self-vote them.
I think (and hope) these will be targeted as well after the first low hanging fruit has been dealt with (Trending).
A quick check in the database tells me he's had visitors, just not from the largest accounts (who are at times Witnesses who would like to keep his / ranchorelaxo's vote)
Every abusive whale can be crushed by the collective.
True, if they got organised.
Number of DVs fell sharply after the first full day...
Most people who have overused bid bots are now very wary of doing that. The low hanging fruit have been picked. It's harder to find DV worthy material now. Sometimes it can be difficult to draw the line between abusive farming and acceptable use of one's SP for ROI. There are no generally accepted guidelines. Using all of your upvoting power on yourself is perhaps clear abuse, particularly now that curators get 50%. What percentage of your upvoting power used on your own posts is considered acceptable? What is the difference between a circle jerk and friends and acquaintances appreciating each other's content?
I'm sure efforts will be organised for this. You need coordinated measures to reduce the risk of retaliation, but I expect they will hit back. I think there will always be some who operate by proof of greed to deal with.
BTW I'm voting up posts rather than comments now as it seems a better use of my voting power.
