was very sad before when grumpycat downvoted one of my posts when they had just newly implemented their rule of 3.5 days maximum for upvoting bots. At that point I had yet to read their notice that they will downvoting posts, and I felt it was unfair of them, like even schools have that "1st offense = reprimand" thing.
I do agree though that probably the best way to go about it is by filtering the plagiarism first instead of just mass-downvoting everyone who tried to use upvoting services during the last few days. It could've been a good post for all they know. Good post. ^^
