It's times like this that I become sad that the world of cryptocurrency and DAOs is so overrun with scams. So often that stuff is a solution in search of a problem. Finally we have a case where there's an actual problem to be solved wrt operating in a legal grey area, but is crypto even up to the job here if there's no obvious profit to be made?
To be fair, if Omegle was operating anonymously on some sort of real-time blockchain, that would make it harder to prevent abuse. But presumably you wouldn't be able to get an app for it in any app store, which would filter out the sort of vulnerable/naive users who are at the greatest risk.
