Reminder about Mastodon "private" messages. Aside from not being end-end-encrypted (and so visible to instance administrators), they CC anyone @-mentioned ANYWHERE in the body of the message (not just those listed at the start).
They are now called "private mentions" rather than "private messages", but if you don't fully understand the semantics, this behavior may be unexpected and/or cause unpleasant side effects.
@mattblaze Honestly, the pm function is wierd and clunky and isn't a proper chat protocol. It's better to just trade handles and chat on matrix or smthing
