This isn't a bitch about ads. It's I honestly cannot easily find the actual information the site is supposedly hosting.
The first question is answered by: https://www.swpc.noaa.gov/products/3-day-forecast (Strongest at Fri 2100-0000 UTC)
How do we call the equivalent of steam-pubk aesthetics but where tech has stopped on pixel art instead of steam?
I prefer it, these ads mean something to the people that run the site, they put some effort into putting them there and presumably purchasing the products benefits the organisation in some way.
They also have a no AI disclaimer at the top.
I wouldn't go that far. They mean something as in somebody was willing to spend money, so this is what they get in return. Just look at the randomness of the types of ads. I doubt there was any "qualifying" of the ads other than did the check clear.
