@prancing389 @SummerBreeze Abandoned in favor of more private/resilient options by privacy fetishists like many of us in the #monero community. True.

a) You'd be amazed how amazingly poor OpSec people have generally, and criminals in particular. A shocking number of *public* social media posts including the accused and the corpus delicti come up in court documents.

Have your Mom try Session Messenger, it does not ask for an email or a phone number, and is a little less complicated than Matrix.
