I remember once upon a time there being talk about a future ability to link multiple accounts under one sole user -- useful for RPing mostly, but also for other uses where posting from your main account or creating communities linked to said main account was not desireable. It would require to be able to choose keeping this relationship between accounts private, but being able to easily change the account you're posting from instead of manually changing it would be a plus.

On the other hand, what about people that claim an account,not tu use it or to later sell it, but to avoid other people using them, because of their personal beliefs? For example, dalai_lama. Would that be considered squating/hoarding? (we're talking about 1, 2 accounts per person, here).
