Well, that sucks. I still am interested in how you seem so sure that it's the Sloth guy, however.
It helps to stay consistent with your core beliefs and values. If you don't knee-jerk upvote every meme that appears conservative and upvote based on the message it's trying to convey, the meme will not get many upvotes and will quickly become irrelevant... making their efforts meaningless.
I appreciate the heads up though. I didn't think people were that desperate for clout.
