Most of the ones I’ve been a part of I’ve had to provide information that proves that I was negatively affected, but there have been a couple that I didn’t have to do that. Generally I think the ones where you have to provide proof lean towards being higher in the amount of money you get, but that’s only my personal experience.

I’ve been part of a class action suite that netted me several hundred dollars, but it was a rarity, most others I’ve participated in ended up with me receiving between $1-20.
