Sure they can. If a suit is filed for $25K, do you really think Equifax cannot do the math of what a default judgment would cost? If all their attorneys are busy, they would hire more. Even if it had to be expensive temporary help, they would hire someone to show up.
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 learned long ago, never to wrestle with a pig. You get dirty, and besides, the pig likes it."
And also that their attorneys, and their attorneys' attorneys, and their attorneys' attorneys' attorneys are very busy right now.
