No it does not. Neither does having a password as they can be leaked or cracked or who knows what. Turning off tcmp echo on your router won’t stop all bad actors but it will stop some. All security practices are just small steps to make it slightly harder for bad actors.
I 100% agree with you. But I’ll also admit that I email people ALL the time and I have no idea what their email alias is. I just hit reply.
I absolutely agree with you that even with a rotation musk’s email alias will get leaked. I’m just agreeing with you that it was security through obscurification and it would have worked if one of the emails got leaked. A thousand people would have tried variations of elon.musk@ i am willing to bet none of them would have tried erm71@
And let’s face it that man has an auto forward on his email lmao
