Please remember to use only use your Pronton Mail accounts for private messaging. Mastodon Social does not support private encrypted messages. I would avoid using the DM feature on SWitter. Proton will always be the safe choice for messaging.
@Fiddy although there may be other secure messaging choices, I would concur about DMs — posts in mastodon seem to be akin to public shouting, except we have these settings that tell all-but-followers, or all-but-those-we-explicitly-list, to cover their ears.
I know that’s not the way things work technically, but it’s a good analogy to get one’s head around it I think?
