No, not really. Not really what attorneys do. There might be collections agencies interested in recovering the debt, but if it's some rando guy who doesn't have the money, even that is open to debate.
I mean I'm not familiar with every debt collection scenario under the sun but Internet randos seem to think this is a real thing where like a cloud/hosting company sends an army of lawyers to repo some guy's house and runs him into bankruptcy because of a traffic overage. I've never seen it work that way, what happens like with most business debts, is someone at the company negotiates with the debtor to try and get as much out of them as they can, and failing that, possibly refers it to a collections agency which does the same but plays a bit more hardball.
In the case here with Netlify even before it went viral they reduced the amount from $104K to $5K, no lawyers, collectors or repo men involved, and while I'd hate to be stuck with that $5K bill, I dunno, that does feel closer to the mark of something that maybe you should be on the hook for if you're responsible for 200 TB of bandwidth overage over 4 days? Is this so bad on the part of Netlify?
All that said I'll just add that I've never given my credit card to any sort of host/cloud who had terms where they could bill unlimited overage fees like this. Never will unless there's a cap. Not Netlify not AWS not nobody. That goes for my personal life as well as for the business I operate. The terms is the terms and the answer is to not use these services unless you can afford them imho.
