Everyone Greylists Except Honeypots ... So Let's Not Spam Honeypots!

Does this notion bother anyone, in particular?

The argument for greylisting is apparently no longer - and if it is, it 
can't be for *much* longer - that, "So what if we can't detect non-MTSs 
anymore?  We can still trap the bad ones by letting our favourite non-
greylisting BL spamtraps capture them!"

So all Mr. Bad Guy needs to do now is realise the significant uptake of 
greylisting for this one purpose, and never spam any host that seems to 
accept all initial transactions.  They can do this simply by not entering 
the DATA state.  And if that's used as metric, by sharing data amongst 
themselves as to the exact purpose of non-greylisting hosts.

Any thoughts?

Cheers,
Sabahattin
