And seduction got absolutely nothing to do with security. It's a simple 
boolean: either Your system is secure (in terms of human calculation[*]) 
or it's not. There is no enhanced or "partial" security ...

And once again: From a more or less "psychological point of view" it's 
even worse concerning the traffic load: the curious "bad guy" would try 
to go on. So it's better to explicitly tell him to go away.

[*] "secure" means:  You have to invest more effort into breaking into the 
system than you can expect to gain from it.
