Realistically, I doubt it's worth more than 25k CAD plus. Seems like a supplementary income/hobby community that alex chooses to keep running, rather than moving onto bigger things. There's no real product being sold, and the income is only there so long as the community decides to support it. I'm sure if alex wanted to, he could easily just made more money by working as whatever he does as a professional.
I don't know how much it's worth, but the cost of entry is having the time and life sucked out of you.
