I was browsing some different trackers for audio books and came across MyAnonamouse. I thought it was strange that for their invite process they have the following rule:

2. No VPNs, proxies, mobile IPs, or public wi-fi IPs are permitted in the interview. You must be on your primary home IP for the initial registration.

Anyone know why this is the case? Is it just to prevent account sharing? Why do they care as long as the ratio is maintained? It seems like a breach in privacy / security to require this.

Thanks for any insights!
