Leak contains emails from 2010-2019, so unclear if this was in use still. The funniest thing I've found so far is that Kash had a business get dissolved for failing to file paperwork with the state of Florida.
@mttaggart does the email address have any dots on it? You know how Google works with those (badly, treats dot and no dot as the same e-mail address). So dumb and dumber go to town and find Kash right there. lol
