I've noticed recently that there are many pages with random letters, most similar within its area, placed in random sections of the source code. I found it also in my User page, which took me some 10 minutes to clean up. I'd like to know a bit more about what is happening, so anyone who knows or has a clue on what happened, please post to let me know.
