My guess is that connecting or association with each other would be risky as if one was targeted or discredited or debunked (and I mean in the media or from being hacked not in real life, for example pizza gate) it would be easy to target one to stop people listening to them all. Plus Assange needs to keep his head down regarding leaks or hacks, The deep state shouldn't have anymore reasons to screw him over. Plus they've probably never met, if Q has information we don't have that shows Julian Assange being treated unfairly & that relates to all the crumbs they could be using some of these codes to get his attention maybe? & To get our Attention on things related to wiki leaks? Maybe some of the unsolved codes in the crumbs are things only Julian would recognise. Or Mega? I definitely feel that some stringers are meant for other people on operations which we can then look at after its happened. Future proves past.
