HUGE problem. Half or more of front page memes are reposts. And these people will claim they thought of the meme first...even when it was done a decade ago. It's pretty comical how delusional some of these people are. Original memes rarely exist within the iconic meme templates. Most ides and jokes spun off those templates have been done and then done over and over...oh well, still entertaining.
I know it's possible to acciently do that. I did that with the grandma can see meme and a marylin manson joke. A friend was like, i remember that meme. But yeah i think that really only happens seldom. But a l8t of these autistic acting noobs are like 12 so what csn you expect. Seems like users on imgflip are older or very young. So there is just conflict with maturiry.
