I was referring to the quatrain that most people know: 

 *The Moving Finger writes,  
 *And having writ, moves on 
 *Nor all thy words can erase half a line 
 *Nor all thy tears wash out a word of it. 

 The images are on WP (whatever the originator's motives), and, even if they are removed, can, like much other 'methods of analysis' can be found 'by those willing to look for them'  - so the process of analysis has been changed and the situation has to be worked around. 

 Any comments on the first three points?
