Some have pointed out that they use an alt account just to make more memes and don't use them to upvote their main account or downvote anyone's accounts. And they pledge that they're going to delete it before it gets on the LB.
But usually, like everyday, people are just making them to troll their enemies and upvote themselves.
That is despicable. And the site will be so much better off once they're all removed. :{D
