Hi - It's Mitch from DigitalOcean. We are still ironing out our TOS. Given that we are still a startup we are always constantly looking to improve the language.
We don't consider ourselves too strict. As long as you are not trying to run an attack or spam/flood our network, we are totally cool. :)
For example, you can't send email to your users without double opt-in.
Yikes!
Not to mention the ambiguous language banning 'offensive' and 'inappropriate' content.
