Do you think those owning crypto related domains should ensure they do not display unsuitable images (and misinformation) because newbie and gullible investors as well as those of all ages youth and elderly could view the pages? Or do you think it is not that much of an issue?
They should not, but it's their site and they can do whatever they want to do with it, I've checked all the contents of the site and they are Crypto-related articles, maybe it's meant to attract mature viewers, but it's a bad move because images is meant to attract visitors to the content of the site, there's amateurism displaying unrelated images from the content of the site.
But the owner is lucky to have Bitcoin on it's domain, the word Bitcoin in a domain now is very expensive.
