The last one on this page is totally legit, the first one is okay, but between them are websites which I categorize as garbages. This kind of websites is a variation of content farm. It's not like usual content generation, but using domain-related data to produce content to fill up the page, so it would look something in search bots' eyes. They will grab all sorts of results via API of other services and gives you some whois information.
That's really for noob to read, who don't know about where to look for information about a domain from the original sources, mainly for their own domain. I don't think one would want to read other's domain information, generally, at least not to read from this sort of trash websites.
Unfortunately, Googlebot crawls and indexes this kind of websites. The time range in the screenshot about was set within 24 hours and the search hit 75 results (and it has increased to 80 while I am writing). Sadly, I haven't been able to use blocked unwanted sites, which is a feature of Google Search. That page has some JavaScript error, it's been broken for days since I've noticed. Don't know where to report a bug except using that community support forums, and I do not want to use that. Just another typical Google support method nowadays.
An interesting point is my domain is not even the focus of the matched results. These websites will put a list of domain names next to basically unrelated domain names, so they can somewhat increase search engine hit ratio. It's cheating, I would say, and Googlebot isn't that smart to know that.
