More seriously, this is a question of personal ethics. A consensus will never be reached.  
  
If wearing a sticky kneepad to stick a kneebar is cheating (aid), then wearing carharts in a chimney is aid too.  
  
Tape is aid 
  
Shoes are aid 
  
If clipping the bolt is cheating, then using a rope is cheating too. Cams are cheating. etc...
