In theory, if Mastodon revealed which country your Mastodon account was mostly used from, it would not be possible for someone to get paid to influence voters from another country by pretending to be from said country.

For instance, Putin could not pay Russians to influence a US election by posting in English from a secret office in Moscow.

Of course the price would be, Mastodon would then reveal everyone's home country.

Would you like such a feature?
