This is an interesting question, and I would assume one they will answer with each character as we cover them in an episode. I'm assuming most of them were somehow unhappy with their situation, and so decided to "pause" what was going on by going to the LOUS. I wouldn't mind some more unique reasoning for some of the characters though, like they were banished there, because otherwise it might get a bit repetative.
