Right after using my hobby burner to attempt some new contacts (non-ECCIE), I got a text with my correct first name expressing interest in purchasing my home at my correct home address. I assume the interest in purchasing my home was a pretext for letting me know that the burner number, my name, and home address coincided. For what purpose? A friendly warning? A pre-launch threat? Advance notice of a shakedown coming?
This is why I use a burner app on my personal phone and then delete it. I get a new number everytime I download the app so don't ever have to be worried about being contacted by anyone. Try Textplus even on a burner phone. It may make some screening difficult changing numbers all the time but fuck it. Also keep in mind that there are shady ways of getting your personal information when meeting a provider in person so just be careful...
