http://foobar.w3schools.com/jsref/jsref_replace.asp http://foobar.w3schools.com/jsref/jsref_replace.asp http://sdfaxdds.w3schools.com/jsref/jsref_replace.asp http://sdfaxdds.w3schools.com/jsref/jsref_replace.asp That looks like wildcard DNS to me. The question is where the linkbacks are coming from. It is possible w3schools is creating those themselves, in which case that does seem like unethical SEO tricks. But if not, well, they can't be responsible for how people link to them.

Oh, I know that wildcard subdomains are valid, but it's simply not possible for people to type these subdomains (http://jsbin.com/upamof/edit#html,live http://jsbin.com/upamof/edit#html,live) by accident. My opinion is that they're trying to use technically-allowable but questionable methods to bypass the fact that people are 'blocking' them from search results.
