The whole thing is kinda funny to be honest :) Besides the whole Grumpy Cat meme photos, you got a vigilante do-gooder in @grumpycat who don't really practice he preaches.

Why don't these bot owners just go the 3.5 days route? It costs them nothing. End of story. I mean, if you take @grumpycat's demands out of the equation they should still do it. Everybody wins, spam loses.
