I reported a few days ago about my daughter's surreptitious attempts to post messages to poetry forums. Today I caught her just as she'd typed several paragraphs of random letters, numbers and symbols into a message-window at the Poetry Free-For-All site (PFFA appears to be her favourite). Luckily she hadn't pressed the button that sends the message for public viewing.
However, I then realised that she was attempting to post it to the "Experimental" forum where it might not have looked out of place. I deleted it anyway.
