Spam-a-licious
"In Fall 2002 Stanford implemented a spam filtering system for @stanford email. The system works by scanning incoming email for spam before it gets delivered to your Inbox. When the system finds email that matches verifiable spam message patterns, it adds a key word to the Subject line indicating how certain it is the message qualifies as spam; then it delivers the email as usual." (http://www.stanford.edu/dept/itss/css/leland/email/antispam.html)
Two things. First, I feel like there's been a sudden and substantial increase in the volume of spam I receive has actually increased since this filter was implemented. Was the publicity generated by the launch of this service a double-edged sword, enticing spammers because they knew their emails would only be marked, not entirely deleted? Also, I thought I remembered a previous schema, under which a lot of spam was actually blocked from ever reaching your mailbox. Were false positives, such as those described in the paragraph below, the reason for the recent absolution of responsibility (turning judgement calls over to the user)?

Second, about a third of all my email marked as spam, isn't. One particularly flagrant case is that all Yahoo! Groups email from anybody without a Yahoo account, and thus bearing overwritten sender addresses, gets consistently blacklisted. Seeing as how [edisonpeople] has comprised a good ten percent of my email in the past week, it's mildly annoying. Humph.

Please don't take whining as indicative of general mood, though! In addition to catching up with old friends, have been happily reading lots and lots of everything, both on- (code =) and ebooks) and off-screen. I'd nearly forgotten how grateful I am for the public library only a block away!
