There's definitely been a drop-off in spam levels over the past week, which
comes on top of a general drop over the past few months.

Although far from a great indicator of global levels, the following two
graphs give a good idea on what's happening on a relative basis :
Past Month -
Past Year -

The numbers for December are especially unusual, as with Christmas coming
it's normally one of the higher months for spam.

The drop-off since September is mainly due to the closure of spam referal company), although I haven't seen any
reports of what's
caused the drop-off in the past week or so.
