How do I turn off ARB?

[element22]

I have to delete 512 ARB subscriptions from our sandbox account.  There is no way to do this in batch form.  I started doing it manually but it's 4 clicks per subscription, plus extra if it's a gmail address that includes "+..." because that has to be removed.

I was told that if I turn off ARB, that will serve the purpose of deleting these subscriptions.  Then I would be able to to turn it back on.  I can't find anywhere on the website where I can do that, though. 

Where can I turn off ARB and then how would I turn it back on?

Thank you!
