User-Defined Voting Bots
Community Support Bots
I don't think there are any good bots. I might let Curry slide as from what I understand is the community votes on what is upvoted.
I personally believe that all upvoting/flagging options should be removed from the API and only allowed through STEEMit.com or an officially approved app.
I appreciate your opinion and you taking the time to comment @deanlogic, seriously. I also agree with you on only allowing those actions from Steemit.com directly.
