It looks quite cheap for someone with a larger family. But there's nothing substantial on the privacy page. I'd expect at least some more verbiage on how data will be handled and won't be handled. It also doesn't state how much disk space quota is allocated, how many mails can be sent, whether each user can choose multiple aliases, and any other limits that come close to what's considered abuse.

Tangentially, it's also amusing to see "family name" so ingrained in so many cultures that it's assumed that people who are part of a family will have a common name. Around the world, this implicit assumption breaks so many things for the people who culturally don't follow these (including visa applications, website forms, etc.). See point #20 here. [1]
