I suggest dbr.ee. Unlimited storage, easy to keep organized with an account, only downside is that you can only upload up to a certain size, but I've been able to upload full stem kits etc (pretty sure the limit is 500mb?)

As long as you give it an obscure name, copyright won't catch it either.

As for banned sites, basically anything that requires a password or a website that has a "premium version" that costs money to download something faster. Dbr.ee doesn't have either of those issues.
