I've recently received a lot of spam through my contact form, and it's starting to get on my nerves. Apparently the spammers have noticed that many developers are trying to thwart their attempts to sneak extra header information into PHP's mail function, so they've resorted to spamming websites directly! (or am I the only one?)
The messages I've been getting actually include a long list of URLs of the form: [URL=http:www.whatever.com]whatever[/URL], so I'm guessing some web app that uses this type of markup has a security hole... Time to patch that up developers!
