Our log ingest has finally caught up, it looks like the home.social site has been effectively DOS'ing us since the 17th with between 100,000 and 500,000 hits per 12 hours.
Given the entire site seems (Unless a #mastoadmin can tell me otherwise) a giant scraper that I've just missed up to now we're going to probably just block the IP and user agent and hopefully that'll see the site get significantly more stable.
