Where should I upload stuff?

So - Where should I upload leaks etc. without them getting removed?
Uploading e-books, files etc. etc. Not illegal stuff but leaks and such.
Also I'd need pretty much space on it, like 10 gb/account.
Also something that people can't see what else I've uploaded on the same account.
I don't want to use Dropbox. What would you suggest? Mega?
