[Privsec] How safe are Plaxo and other online address books as protections against tracking?

[Claude Almansi]

Hi All!

Yesterday I received an e-mail from a human rights militant in a country
where the internet and e-mail are heavily monitored and censored by the
government: she sent it through her Plaxo address book as a security
measure.

I don't know much about tech, but if this is a safe way of avoiding
e-mail monitoring, then this could be a legitimate use of online
address books, maybe?

All the best
