Is Sargathon A Scam?

Yesterday I posted about an event in Canada to raise money to help a guy’s dying mother.  But I’ve been getting emails from a lot of people that this might not really be as "on the level" as it seems.  Here’s an email I got from someone today who wishes to remain anonymous, but seems to be a highly credibly source (I took out his credentials because he didn’t want to be identified):

Hi Thundercat,

I have been subscribed to your RSS feed and/or newsletter for as long as I can remember.  Snow is a crook.  This is a scam.  The last time my stomach flipped like it did this morning when I read "Snow’s mom is dying of cancer" was when some idiot told me to go watch "two girls and a cup".

Snow is a complete and total con artist.  He was indeed ejected from the lair and caused the great divide when he reneged on paying his referral fees after convincing the Lair to force new students to attend to stupid workshop.  I attended it in fact on a whim and left at the first break never to return.  He had literally photocopied competitors materials and was charging for presenting the information.  If you think Tyler is bad you are in for a very big shock when it comes to light that "my mom died and I spent the money on unforeseen expenses for the event (and going to bars every night)".

So is Sargathon a scam?  Is this Snow guy really using his dying mother as an excuse to bilk some people of money?  I certainly hope not!  That’s low.  Does anyone have any proof that this event is legit and the money will actually go to this guy’s mother?
