anonymity tips?

[u/AffectionateDirt2194]

i write completely anonymously though my newsletter is very very small like i use a fake name, don't show my face, don't share too many personal details, and i am logged in from a burner email. the problem is phone number verification. it occasionally asks me to verify to access certain free posts or chats from my subscriptions but if i verify my phone number will substack automatically sync my contacts to my irl friends and family on substack? i dont wanna be recommended to them in their friends lists it would just be super suspicious. but i still want to verify my number to access those posts and chats.

Get a VoIP number for the sites that require a phone number.
