This system will fail: i explain:
 A.
   1. Figure one send 10 messages asking a couch, for two week. This 
is reasonable and is likely that will be good personalized messages
   2. One of the people reply imemdiately saying "ok, but please 
confirm me within 15 minutes that i am leaving" and since is in hurry 
forget to click on "this is not spam" . The other people cannot reply 
immediately.
 B: one could forget the count and send many requeast for a long 
period, and end not being able to reply to the first reply since has 
queued too many good messages.
 C. 
  Having two button "this is spam, this is not spam" is easy that 
someone use the wrong one.
 D.
  One could act politely at the beginning, once released do spamming
 E.
  Many could send message to people just asking to be approved for 
sending messages, so to get the clicks.
 F. 
  Some people read messages only wia e-mail, and go to site only to 
reply, so if the message is just informative (or just a "thank you 
for your attention") will not be clicked.
 G.
  unprivileged user will not reply "thank you for your reply, even if 
you do not accepted me" for fear of using thir limited amount of 
messages. 
 H. in case of a new user there is even the worse risk that he do not 
even reply to requests that would not accept, for the same reason, so 
even the "no spam" button will be never pushed and people would avoid 
to use BW since their bad behaviour
 I.once approved as good fellow one could send spam at will.

this is a bit better, it is what [see my next reply to peter Lind] i 
am proposing.
