Doublelist Is Using My Phone Number Without My Permission

Since 2021, my phone number has been used on Doublelist without my knowledge or consent by a person named Christopher Lesemann, who signs me up for random hookup listings. I have never given permission for my number to be used on Doublelist and I am extremely uncomfortable and distressed that my number is associated with these types of ads. I am requesting that Doublelist permanently remove my phone number from its system and block the email address used by Christopher Lesemann from ever using or adding my number again. I also want my number to be protected so that it cannot be re‑registered in the future without my explicit and verifiable consent. I expect this issue to be handled urgently and for my privacy and safety to be respected.
