Also, some of the forums discussed aren’t active anymore; therefore, the relevance of their data is out of the question.

Previously, DoubleFlag was selling millions of “U.S. Cellular” customers data and 1 billion accounts stolen from Chinese Internet Giants. His feedback ratings have been positive throughout which means the vendor has been selling legit data to buyers.
