Well to be fair DigitalOcean is a pretty big company, they're funded heavily. I would presume they won't take this hit sitting down. Unless you're truely confident that they cannot find you then you better start thinking of your plan. If you used your real identity then just do a payment plan if you cannot afford the whole bill at once. If however you used a fake identity so thats either fraud or false misrepresentation, then you'll likely get a knock on the door and a confiscation of all your electronics.
Don't drop the soap.
Also to note if they really are pursuing this, then someone may send them this topic and then oblidge OSBot to hand over your personal data. So now you're actually fucked, rippp.
