For those who don't know, you can get this list in near-real-time (only a few hours delayed) at https://usesteem.com/steemwhales/topauthors
Keep in mind there is a lot of differences between some of these authors. Some get there without any bots and are 100% profit (i.e. Haejin, Traf, Steemcleaners, raindrop, and others), some heavily use bid bots (most people fall in this category).
Although there are a lot of the same names on the list, the list varies quite a bit daily. Some go in spurts, others are systematic and are near 100% consistent.
Most of them are posting pointless dribble but rarely ever get downvoted.
Usesteem will show the top 500 authors updated every 8-12 hours.
