Yes. And that's the way around restrictions on class actions. Where the victims are identified and cooperating, and the cases are very similar, it works. There are some lawyers using this strategy. Huge numbers of cases are filed, they're all consolidated by a judge, and the end result is a suit on the merits.

The filing service needs to do more of the work, like shipping the paperwork off in bulk to a process server company to be formally delivered in daily batches.

Yep, and Equifax will hire some local firm for a small amount to take care of all of them that day.

I wonder how quickly / ably they could scale that. What if every US-based HN reader filed a suit?

Even better, what if every US HN user filed a small claims court case? I believe companies cannot hire lawyers to represent them there, they would need to send employees.

I'll go on the record and say that Equifax makes subpar quantitative decisions; i.e. cannot do the math.

And also that their attorneys, and their attorneys' attorneys, and their attorneys' attorneys' attorneys are very busy right now.
