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. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Nov 10, 2018, at 11:26 AM, Dauer, Edward <[email protected]> wrote: > > Before the authorities close this useful but somewhat-OT thread, I would > share one anecdote told to me to be true, though I can't personally vouch for > it, about an unnamed university twenty-plus years ago.
