Sometimes repost are on accident. I have done it a few times, not on purpose. When it did happen, the original poster called me out on it. I ask if they want it deleted, they said keep it up, maybe mine will do better. I, for one, can't remember all the memes posted. But, I'm not on every day like I used to. It might be time for a "repost week". It's fun the times we had them. It repost ones that you have that didn't do good, or a friend's meme on the site that you liked.
