Direct Messages are accidentality to self (user forgets to add name or misspells it which is easy to do).

So a symbol or box or exclamation or self note system can show message is just sent to self and not to anybody

Often people think it's sent (but not to anyone else by self so distinguishing can be very useful for catching mistakenly send messages to self)

Also wrote more here about how to check it yourself (like double-checking):
