I've been sorting out some 2012 data files the past few days, and amongst the vastness of all the rar files... I came across a handful of trap files and complainer files hidden within good data. Not sure if the data guy was doing a favor by adding these, or made a mistake... either way.. Heads up. Don't just unzip your files and start extracting emails. Take your time and scan the list names for bad apples! Even if you fully trust your source! -Postmaster .
