It's a bot, I'm the human running it.

The bunny only started watching your votes at the time of registering you as a new user (usually within 24hrs after making a delegation) Most votes go to new content which will only be handled by the bunny ~seven days later, shortly before payout. So it usually takes about a week before the first fluff happens.

I checked the bunny's stats (this is available on discord) and you'll see a bunch of dust getting voted soon.

as well as your first one having happened a day ago

Evebn after withdrawing your delegation, you're now permanently enrolled and you do get the bunny's newbie plankton bonus, too. You'll be able to enjoy the "basically-free" version, which comes with obvious limitations in volume, but you will see the bunny working for you 😜
