I can guarantee you this is true.
In addition to the normal rise noted in the
article, someone on the list (here or BC) managed
to be attacked by a virus. Aside from the normal
10-12 spams a day to each list that gets past the
first set of filters, there are now 4-8 emails WITH virus or trojans attached.
That is one reason why, especially now, we try
not to let any graphics, html, or non-text
through the list. Plain text is our goal. To
the extent you set your mailer for Plain Text, you are helping the situation.
Of course, is MUST come to a point where the
sheer volume of spam leads the airheads who "run"
the Internet to finally agree that most anonymous
email must stop. If someone comes up with a
better solution, they will be very rich!
