For anyone presently managing communications for the #JoeBiden #WhiteHouse or the Biden #political #campaign: If you're scouting out Mastodon to determine whether it's a viable option for publishing or broadcasting official messages, consider this: Host your own #MastodonInstance. Let the fact that you're hosting it, serve as verification for the accounts that use it. That will make it much harder for anyone to successfully impersonate your official accounts. I'm sure there are #MastodonAdmin folks here who could help you out with details.
