I don't know, I think it would be a better idea to create a bot that takes people's delegation to downvote GC or to upvote victims, instead of collecting down-votes with posting keys from lots of minnows.
As a minnow, I really can't afford a 100% downvote from GC, yesterday I just got another -$10 on my post because I used the bot and put a flag on GC's comment... I have to say it's frustrating.
To be honest, @the-resistance and the downvote bot can barely affect GrumpyCat, I think it would be a better idea to use those SP to help victims.
