No, ephemeral usernames are not differential privacy. Differential privacy is repeatedly sampling a database through a differentially-private interface which returns data samples which are either real or fake. The mean and variance of the sampled data match the true mean and variance of the dataset according to a system-defined epsilon value. The end user isn't able to know if any given piece of data is real or fake. I really don't like differential privacy.
