/ic/ - Artwork/Critique

i entered a group about some famous-not-famous artist were their fans (some of them) get angry with him for leaving and erasing all of his stuff from the internet, like really disappear, and there was a guy who get really pissed with him for not being thankful enough to his fans for the years they were admiring him, some others say he should have his reasons to make it, the only thing he said before leave was that he have personal problems and for a long hiatus finally he erased everything

i see a lot of japanese artists doing this, erased everything and start all over again, even if they were frigging famous

so what do you think about those artists who disappear overnight?
they have to say what happens or not? is it okay or disrespectful?
would you do that? and if you already did , why?
those who make this desition should announce their new page if they make a new one?
