Scrape a single domain for email addresses(no protection)

Very simple, there is a domain with lots user made pages where they write their emails in plain text (no protection) Very rarely with (at)something(dot)com kind of obscuration. The domain is huge has a lot of pages but only 40,000 or so users and published emails will be significantly lower then that. Please quote reasonably. If you have the tools already its just a matter of crawling this website and extracting emails. I will let you know domain in private message only.
