Since the EIP, buying votes has been heavily and publicly frowned upon and is a major reason that the fork happened to begin with, to discourage vote buying.
That's what I've been told repeatedly, but only the small fish seem to be getting punished for it.
For example,

other than them transferring everything out to binance, I don't see any transfers to buy votes. rocky1 has upvoted me occasionally in the last few months too, I think when high on VP.
If you want to know, you'd have to go through the accounts of the voters and see f there are any sends from other accounts buying for this one. However, last week someone bought me a vote from somewhere too, so that isn't foolproof either.
The last purchased vote I could find for @steemyoda was on page 9, about 30 days ago.
Yeah, I don't think that many are buying votes these days and of they are, they are relatively small. I don't track it though. I think there is still a site that does somewhere.
Let me know if you remember the link!
