So I checked out the website out of curiosity. It looks like it hasn't been updated since the early '00s and seems pretty sus. The section which details their payment is full of grammar mistakes, like it's been poorly translated from another language,
That said, more info would be needed. Do they want you to be exclusive? Want kind of royalty pay are they offering? Do they do any advertising for it? If you're actually considering working with them, make sure you get enough information to be confident.
Judging off that page I mentioned earlier, it seems like one of those sites that causes severe burnout because they expect you to constantly churn out thousands of words a day, EVERY DAY, if you expect to make any money. Basically they want to scam young writers out of their work and hope they can sell it off for a contract which they'll pay the true creator a pittance for.
Even as somebody who signs most non exclusive contracts just so I can respond to forum questions like these with real knowledge, I would give this one a hard pass.
