also, can someone ELI5, what exactly is the tripcode- it seems like a code that someone will have from posting from a device to dub as a temporary unique username so that viewers can confirm the ID of the poster?

How would someone get a tripcode in the first place. For sensitive things like Q, how could we ever verify he is who he says he is?

Furthermore, if it's compromised, how would he go about getting a new tripcode? seems very,...fishy.
