I'll take my chances.
Most rude/lazy people do

NN isn't fulfilling the purpose it was created for if 80% of its target audience is excluded just to protect the feelings of the few people who make alts and don't want to use a command created specifically to deal with that.
Or you could just like, message them instead of blind inviting. But nope, according to you that would apparently make the NN break down and cease to perform its function.

Being polite is hard, folks. It's like the NEW new endgame.

Irritating people with blind invites or pressuring shy/reclusive players into feeling obliged to stay is not a very kind nor considerate thing to be doing and if anything else seems too troublesome for your tastes then I would question if Mentoring is for you.
Oh yay, someone gets it.
