Not a lawyer, but have been sued by a big company like FB. Also know quite a few dudes who had the same happen to them (think CL). From what I gathered, it's one thing to get a default judgement against someone for 6-7 figures, it's a whole other process actually trying to collect it. If someone has no assets, doesn't drawl a paycheck, has no money in the bank, they are judgement proof. That is until, one day they suddenly become wealthy, and they are waiting. Most states have statutes of limitations on how long someone can chase you for that debt. Most states are 7-10 years. So if he wants, he can stay under the radar until that time frame is up, and then tell them to fuck off (pretty sure they can file a motion to extend time frame, but again not a lawyer. Calling Aaron Law!!).
My guess with this case is, they don't give a shit about collecting the money. The amount will be insignificant to them. It's more about making an example out of Mrunin. I settled in my particular case, but I know dudes who let it go to judgement, and the company never pursued avenues to collect the settlement. It's all about the perception of fucking someone's day up, so others will be less likely to do the same.
Just my 2 shitty cents.
Instead of waiting 7-10 years, why not just dissolve the company and start a new one that can't be sued?
