Who really runs a site – with short description
whorunsthis.host
whorunsthis.host
Also, I've tested with news.ycombinator.com with good results, but then I tried with whorunsthis.site and it said "Whoisguard, Inc" accompanied by the YCombinator description. Oh, and the WTF button stopped working.
Hope this helps with something :)
