No--but one way some people get points is that if you upvote ANY meme of theirs they'll go to your Featured list and upvote ALL your memes. Some people will upvote EVERY "latest" meme that has more than a few views, figuring that some of the people they upvote will come their featured list and upvote all of them.
So with those it's basically, "I"ll INVEST my time in upvoting a few memes, with the mindset that I'll get a RETURN ON INVESTMENT"--they couldn't care less if the memes they're upvoting actually deserve an upvote.
