Imgflip, instead of dealing with the root cause of downvote fairies, is I guess trying to handle it a different way. They should find ways to stop downvote fairies, like requiring an upvote on another meme before allowing a downvote, so the votes are spread around (like a net positive for each account). I'm sure there are ways. Downvote reputation as well to prevent accounts downvoting multiple times in a short period of time. Hiding dislikes is just wrong...
