This is a great tool to catch these blatant self/proxy voters: http://www.steemreports.com/trending-comments/
Yes, Steemit Inc. should delegate at least 3-5 millions SP to few moderators to counter these abusers. Can somebody with connection to @ned or top witnesses (@jesta, @timcliff) reach them? It is getting beyond the realm of absurdity.
What makes you suspect they aren't not only aware of it, but are it?
Not saying they actually are, but that there's no way to know they aren't.
I'm pretty sure the bones of Steemit were made for this purpose. Actions speak louder than rhetoric.
