https://www.newsy.co (a tool to turn your un-used domain into content-aggregator like Reddit)
I launched monetization for both of them early this year and things have been slow but steady - looking forward to developing them more in 2021!
One thing, the Monetize help link doesn't seem to be working. Going to 'https://help.newsy.co/monetize' results in 'A slightl problem, let us check.'
Also, I just set it up for one of my domains, and am getting the same error message: http://news.puppy-snuggles.com/
I googled the error message and found the same thing on other sites such as his one: https://www.vanguardist.com/content/go/787290?
