Where is it in law that stipulates that it matters who's doing the recording?
Though this raises the question of whether companies that don’t accept 2 way recording but mandate 1 way recordings to their advantage are companies you should do business with.
Customer service representative: "For training purposes this call is being recorded. Are you okay with it?"
Airbnb member: "Well, you know if you feel comfortable that we record this call for quality purposes, I'm totally fine with it, no worries."
CSR:"Haha, sure I am. I just have to ask, you know."
AM: "Sure, me too, it's important to me that you're comfortable with it, too. So... here's the issue why I'm calling..."
You'd still have yourself to blame if you naively believe everyone, but is it legal to present evidence obtained in bad faith? Can you blatantly lie and say the recording is automatically deleted after a minute, and still present it in a court of law?
Seems that little bit more sneaky!
