Well:
> It was sent by PhishLabs to DigitalOcean, and DigitalOcean forwarded it to me.
I don't think this is the first complaint from PhishLabs to DigitalOcean. I do think DO would have "investigated" up to the level where they'd click the link and see "yep, that's a google sign in form". It's not up to DO to dispute claims made by people who send them abuse e-mails. As for the dispute itself, we all seem to think the IPFS was not hosting the content. But I'm not sure if that holds up in a legal case (the PirateBay is also not hosting any illegal content).
IPFS has no knowledge of the illegal content whatsoever, it all comes from the URL fragment and Microsoft Azure.
I wouldn't trust DigitalOcean with this fire first ask questions later approach especially given the technical nature of OPs setup.
