I kinda doubted their ability when I searched for a certain podcaster who had them for an advertiser. One of the personas on the podcast never appears on screen and I like putting a face to voices. 5 minutes later I found the person's name, and their work site with a photo. I was just curious and know some Google fu. A malicious actor could do so far more quickly. So at the very least, they don't provide their service to those whom advertise on their behalf.
