Yes, I am having this network (spanning at least 5000 accounts) on my desk as well.

Luckily, the income stream of this operation has been cut off by 95% percent already. These accounts are having trouble continuing comment-farming due to initiatives like @sadkitten and are moving over towards what I'd call curation-farming. A lot of people have been surprised to see waves of upvotes hitting their posts unexpectedly.

I am still working on connecting the dots about this one, I will post about it soon.
