Histograms of the daily posting rates of accounts in the GT, DS1, DS2, and RANDOM HCCs (FSA_V, $\gamma =15$). Because the datasets cover different periods of time, the posting rate enables a fairer comparison. The distributions of DS1 and RANDOM posting rates are similar and notably different to those of DS2, while GT includes a higher proportion of more active accounts than the other datasets
