We recently received tons of E-mails regarding Google webmaster tools registrations for user hosts of yDNS. The affected hosts were used to provide link collection landing pages and these sites were registered on Google to get better rankings. Unfortunately we have suspended the accounts having such hosts and removed the affected hosts respectively.
We will now review all user accounts and hosts on a monthly basis to ensure that the service is not abuse for this kind of activity. We want to keep the web clean and free of disruptive offers like these link collection sites.
