Can you say more about how you detect that people are leeching your site content and how you prevent it. For instance what specific rewrite rules or other techniques do you use to help defeat this type of behavior?
Do you automate the leech detection? I'd think it would be pretty tedious to periodically manually inspect the logs looking for this type of behavior. Do you have a cron script that periodically checks for certain logfile entries? If so would you mind sharing some of it or some techniques used to detect the rogue hits?
Finally. Is there any way that one could "inject" "id info" in site content / pages and then later do a google search with those "id tags" to see if any other site pages have been spidered under those id tags? I'm thinking that if you injected a really unique id tag in the html code, like an element attribute that wouldn't be displayed, it might actually get flagged by google. Just a thought?
