What I find weird is how this particular group seems to still be operating in plain sight on the internet. Their website is still up and has a phone number to call for tickets. Doing a Google search for the name of this fest lists ticket websites with information, Facebook pages, event notices, ...etc. Lthforum's event notice (that is still up) is actually the 4th search result returned.
There seems to be no information available about anyone actually attending one of these events or that any of them actually took place. It's also odd that the only way one can find out that something isn't right about it is to drill down into the individual Facebook posts. One can follow the posts by people who are at first excited about the events, who then defend against the scam claims, and finally realize there isn't going to be a fest.
I would have thought that there would be more of a hue and cry on the web and news media about this since it was several cities, spread across several months, with the last one being held near the end of October. I suspect that there are several people still expecting to go to one of these "events" who are in for a big disappointment.
