Interesting case and a brave initiative. To get damages payed, to what level do you have to prove that your loses were incurred by the 'crypto ad ban'? I assume it will be difficult to demonstrate that no other factors where of influence (non-spurious relationship between the ad ban and the bear market). Or perhaps it works in a different way?

What of their defense that they were acting in good faith and protecting their users from the many crypto related scams that used their advertising tool to be more effective.

Good luck in the case, will follow your updates!
