I have seen so many different approaches to ingress be responded to by Lemmings as inappropriate or creepy, much of it hypocritical to other responses, but I digress: is there ANY appropriate way that everyone can agree on for convincing humans to invite you past their threshold?
From the collective consciousness of Lemmy comments I have read, my impression is that the only appropriate thing is to be born into a coterie with thralls already and never make any moves or even so much as look at a human in your unlifetime.
It is not worth bothering. Humans have a test where they show their teeth to each other. Sometimes accompanied by a hoh hoh sound. If you do not pass this they will not invite you to their private chambers.
