[Elecraft] Spam filtering

[Walter Underwood]

That did used to happen with brute-force algorithms.

For the past 15 years or more, spam filtering has been an arms race. Spammers automiatically open a bunch of email accounts on a free provider, then have scripts try different variations until something would get through. Then they hammer the service with that spam until it was blocked. Then try again. Spam can evolve hour-by-hour to find weaknesses in the algorithms.

Similar stuff happens with spiders for web search engines. I’m glad to not be in that business any more.

The IT department decided to install filters that would block both incoming and outgoing e-mail that contained offensive language.  So they made up a dirty words list, not telling any of the clients what was on it or even that it existed.  It was discovered when the Political Science Department got no responses to its e-blast announcement of a conference titled something like "Contemporary Issues in Capitalism, Socialism, and Communitarianism."
