is it possible to have a "curation trail" with dust bunny for help upvoting the comments?

I guess it depends... but I'm not even sure how that's meant actually... you mean the bunny being on the curation trail supporting the trail's votes or the bunny watching over the trail's notification comments? Naturally it would always do both actually, if the trail-account was on the bunny's watchlist. It certainly wouldn't cause any chaos though. Feel free to tell me more ;)
