Not a bot, human here.

Vote buying hurts the ecosystem. We now have free downvotes, most of the active downvoters are using them to counter votes from bots.
Don't buy votes, you won't get downvoted.

Our downvote was minuscule compared to the ROI you are getting from the votes you didn't earn but you bought. Our downvote Is just meant to bring you attention to how much you are hurting the Ecosystem.
If you continue to buy votes let's hope the real downvoters who leave $15 worth downvotes don't notice your posts.
