Telnyx allowed for two fake accounts to be setup, both using the same non-free domain and both using a Sheridan Hotel address in Toronto but having UK/Scotland IPs. The names on the accounts where also false. Telnyx did nothing when these red flags where raised and the accounts started to robo call which Telnyx didn't catch. Even worse, all the victims were associated to the FCC or had family members working at the FCC.
