Yes I have been following the site pretty much for the last few years.
It has alot of issues but the owner isn't a scam artist.
My guess is, like with most men. He opened up the site years ago out of pure boredom, then he found a girlfriend, then married her, then had 1 kid, and then another kid and basically no time anymore to maintain the site.
It made good revenue probably in the past but not enough for him to quit his dayjob and do it full time. Hence why the updates and support is very slow.
It would be better for him to sell the business to someone else than letting it die.
It will be some time before this site dies, from what i can tell they have a big share of the dice market. My guess is the low house edge gets a certain share of the market and they have no real competition. Big difference between 0.5% and 1% house edge.
