Someone recommended that email was a more "anonymous" protocol. That really
depends. Most email servers, by default, forward the client IP Address in
headers. Make sure you are using Tor Browser with webmail or TorBirdy in
Thunderbird if you want to use email "anonymously". Going to add at best
email is a pseudonymous protocol. At some point there is an identity,
ideally it's not linkable to you in real life but... Gmail for example
almost always requires you register from a residential IP Address and
verify a phone number - I won't even call Gmail pseudonymous, it's directly
linkable to you. The prepaid burner phone argument is silly - anyone
