Mass leave communities

Hi All,

Someone got into my account last night while I was asleep. Reddit did it's thing and spotted it and locked my account and I've locked it down now, new password etc.

Before reddit kicked them out it seems they joined dozens and dozens of NSFW communities. I've been leaving them, but it is a bit soul destroying having to go into each one and see the photos or videos to leave each one. Is there a way to mass leave without having to click in each one?
