The problem I had with both those terms is that they're not anonymized (and unless the usernames are obscene, bowdlerization isn't really a good fit). With the other leaks, at least for the older accounts, a name can be associated with these charts. For the newer accounts or those that lay dormant for a few years before trading, I suspect those who have been logging the web socket and IRC traffic could create a correlation with an individual.

Anonymize is probably fine, but I want "reversible anonymization". :)
