It actually doesn't really bother me, especially with memes and random internet content like that. I've seen posts on Reddit that were actual art, where the title of the repost implies the poster created the art and that it's not a repost. It's lame for a few reasons, such as commenters trying to engage with the alleged creator and the OP not replying, then people finding out it's a repost, etc. But, honestly, whatever.
