>>50338421) people usually don't up and quit with no warning unless something big happened, I know some studios don't let you post online/personal work due to contracts, but being able to say you have work now is not against a rule
2) people dont up and leave every way you can contact them without warning for prolonged periods of time.
3) if people are dying/thinking of leaving, there is usually some indication ahead of time.
granted, an emergency 'hey, I died, so here are my passwords so please post something to inform people' is an oversight almost everyone who isn't a known person does.
