If a random people files a complaint, the lodge will investigate. But it will be a little bias on his side, a mason is a brother to a fellow mason. So they're brothers but not the complainant, who will you rather be with? Even if the lodge don't tolerate it, it will be the way of life out there. He passed the rituals, he passed everything but the complainant is just some random fag on the doorstep with a piece of paper. The Lodge and it's members will vouch for him until proven "guilty". In which case this will be treated as a case of a business falling down and it is inevitable, it happens to everyone. Having said this, if he is a real mason then brothers will help him get up.
However keep in mind that if another mason files a complaint about this issue, whether locally or international then that's the time the lodge will investigate without any so called brother bias. But Goodluck finding another mason that has been ripped off, there will be none. But why go this route when you can easily get into court right?
I also doubt that he is a mason if this scams/fraud are real. First of, scams and frauds are NOT Tolerated in ANY cases and not done. If he really is a freemason he will not do any of those fake wire transfer and show it to everyone and some scams he pulled out about a "New women partner" using an avatar without the permissions of the girl just to fool everyone and get more money. Honesty in any business is a must for all freemasons, how you think, how you react and how you treat everyone. Some will have flaws but doing it intentionally is not a Masonic way of building a business.
