How so? He was after a way to slow John Q's box down to the point where he would

botnet/spammer code I've looked isn't overly complex. it's orientated to sending 
UBE/UCE, nothing more. Most of them leak memory live a seive, so holding a 
connection open will cause the box to behave poorly, therefore prompting John Q 
to get a rebuild
