Using SteemRewarding people can follow both your upvote and your downvote trail, so they can come behind you to help remove rewards off those you downvote.
*Disclaimer: as long as they agree that you are downvoting responsibly, automatically downvoting is a serious thing and really I only DV trail steemcleaners and SFR because at least those are all DVs that have been approved and in agreement with other community members that they are deserving of a DV (and neither of those communities approve DVs strictly for the author using a bot, for example..) bot abuse is a different ballgame though
If you are the equivalent of steemcleaners for the #dporn tribe then I would imagine following you is responsible.
Using @rewarding they can scale their vote weight from yours (if they set it to 200% of your weight, when you vote 50% they will vote 100%), set maximum votes of yours to follow per day and per week, set included/excluded tags and included/exclude voting on certain authors, and also set a weight threshold to not follow any votes of yours below a certain %, and so much more!
SteemRewarding is the best autovoting dApp by far!
