Specifically offensive (i.e. racist, sexist, homophobic, etc.) memes, I could understand someone being too cowardly to attach their username to (but why make them if you won't own up to it?). But I'm seeing just regular (though well-done and humorous) memes posted anonymously.
I mean, I'm the MOST HUMBLE MAN IN THE WORLD, but COME ON! There is such a thing as too much humility.
