Flash Fiction Online gets a fair amount of comment spam on its fledgling users' Flash Forum. You wouldn't know it though, since it is swept away immediately. It is disheartening to note that malware and spam technology has become so advanced that it is now offered as a service. You can buy a host computer all mal-ed up and ready to infect the world.

On the positive side, it should be possible to create countermeasures. I expect there will be a lot more attention paid to cyberwars and cybercrime by science fiction writers.
