Barry has a reasonable theory - that the economics of spamming is brittle -
but it is just that: a theory.


Part of the theory itself is generally sound. If spamming isn't making
someone money, much less spam would be sent.

However, the assertion that the spam economy is 'fragile' doesn't really
hold up. The number of spam emails hasn't substantively decreased in a long
time. Year over year, it's generally flat to increasing. ...

I'm still seeing 90% spam but many people I know say that it's dropped to
more like 50%.  My guess is that the spammers have just figured out how to
do it a little more efficiently.  50% is still awful.

T's,
John

PS: my system is small and strange and has a lot of honeypots so I'm not
surprised spammers keep trying.
