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!
