From what I know, there was a time limit about refunding, at least one decided a year or more later she was “dissatisfied”, but also back out of the lawsuit. Also, again IIRC, the lawsuit involved scum lawyers trolling for a class action, who were later disbarred for other reasons. He may even have refunded some, I have no idea.
I read some of the linked site, but not every word.
The fee was $15K. She stuck in there for $800K in legal fees. Who does that?
