While browsing the spam tokens reported by SpamBayes, I realised that spam messages often have the same words, including typos and deliberate mispellings. As described in Paul Graham's A Plan For Spam, it's pretty straightforward to detect spam once you have trained your spam filter. Spammers are victims of their own dubious success; the more spam they send, the more duplicates each person is likely to receive and hence identify automatically as spam. Unfortunately, not everyone knows how to run their own spam filter. Heck, I've been online for years but only just started my own filter.
Julian asked why spammers think anyone would buy mortgages / fake watches / online diplomas / genital enhancements / medicines from a stranger based on a tacky and badly spelt message. Other than the obvious response that enough fools actually respond to spam to keep spammers employed, perhaps enough people accidently click on the spammer's link to earn them advertising dollars!

After moving all my stuff to my new web site, I thought it'd be simple to redirect all the visitors from the old site to the new one. After some false starts, I found that the easiest method is the following:
- Create a moved.html file with <META HTTP-EQUIV="refresh" content="5; URL=http://kamhungsoh.com">.
- Copy moved.html to index.html.
- Create a .htaccess file with this rule: ErrorDocument 404 http://members.optusnet.com.au/khsoh/moved.html.
- Delete all files and folders on the old server and upload the new files.
After more procrastination, I finally got myself a domain name. Registering a domain, buying a host service, transferring my pages and blog to the new domain was a bit time consuming; luckily I could consult people who have done the same thing for advice.
