I'm not sure about that- unlike social network data, there isn't a publicly availible dataset containing the names of all the people in here which could be used to de-anonymize this data.
You can also look for specific people in there if you have certain kinds of prior information about them: For example, Aravind Narayanan was able to de-anonymize some part of the Netflix set [http://arxiv.org/abs/cs/0610105]. Maybe that won't translate to this data.
