You're the second person who doesn't seem to realize that fraud prevention requires proper actions before and after fraud is detected/suspected. Failing to react properly on fraud protects the fraudsters - like CashApp has done - and makes the platform a magnet for fraud.

CashApp failed to investigate and provide vital information to victim while she was being investigated - they did that too late only after they were compelled to do so by the court and lawyers, creating a very hard situation for the victim and allowing the fraudsters to cover their tracks.
