I wouldn't worry about reposts, like Hokeewolf's comment says, it's not intentional. I made a pie chart joke a while back saying that I spent more time googling to make sure my memes were original than actually making the memes. Socrates pointed out that you'd never post anything then. There's a lot of clever, funny and talented folk all trying to make jokes, often on the same topics and with the same template so it would be more surprising if the same joke wasn't made at some point.
