The vloggers most likely do have some liability for losses of the victims. If the U.S. Federal government decides to step in and investigate, then it's lights out for these defendants. I doubt that the attorneys for the plaintiffs would even bother to file a lawsuit if there wasn't a good cause of action in the first place. However, we can't know if there is a solid case without doing proper legal research and determining whether there is any precedent in similar cases filed in Florida. I suspect that there is. But again, I haven't done any recent legal research on related issues. It would be interesting to know if the defendants even have any assets and money in their names to even attach in the lawsuit. After all, a judgement is useless if there aren't any assets and money in their names. The attorneys will end up getting more of a pay day than the victims do.
