I'd consider this vote selling. The content also seems interesting - as while not an expert on it, it looks like a lot of it is spun content at the least. A lot of it (no matter the account) follows the same format too. Seems like a scheme.

It would be interesting to see the percentage of their vote going to buyers donators is - perhaps someone will have a look. From a quick look, every post in their trending has a 50% bene added - so that pretty much says that they aren't looking for other content at all.
