Recently one of my friends got email hijacked and whatever entity it was seemingly used her past sent emails as a training corpus to construct some very convincing pleas for donations involving a dog rescue she's been operating for several years.

These are NOT Nigerian prince scams of yesteryear; this is something entirely different.
