Hi Jeannie and Faraz,This is a common blackhat technique...As Jeannie points out, it uses the pages' visitor's IP address so it looks like THEY are submitting/pinging the URL.
For those so inclined, this would work well with the RSS blackhole. If you follow the posts I've made on this forum, you'd consider this a "high risk" strategy and use it to get your tin sites indexed/linked...Then point links from these tin sites to your money sites.
Jeannie...Nice find on the code generator.
