They've been around for years. A while back a few were sometimes beating SO in google results, but google eventually fixed that. Everything on SO is cc-by-sa licensed, so as long as the source is attributed (and it is on some of the sites), it's legal. The motivation is simple: the clone spam sites have ads on them. They're not actively trying to attack SO; they're just leeching value.
I guess it's a win-win situation. Stack Overflow's ranking goes up, because of all the sites referencing it, and the spammers make money. But as a consequence, the users have to sift through spam results.

#13Google could check when it saw something, but that won't work against fast scrapers. For that, you need trusted timestamps.
One solution to this would be to have a few time-stamping services. You send in a string, probably a hash, and it adds a timestamp, signs it, and sends back a signed result. Then provide a WordPress plug-in to use this service, hashing and time-stamping each blog entry, and putting the result in the HTML in some standard way. (Perhaps blog entry ). A few mutually mistrustful services for that would help; blogs with serious forgery problems could use multiple time-stamping services.
Search engines then need to look at timestamps as a rating indicator. If two results are very similar, the earliest one wins.

#14I don't understand why StackOverflow allows this, yeah creative commons is cool and all but it IS NOT COOL for actual users. I get so annoyed every time i search for something on Google and it leads to an its clone site. It's not like StackOverflow has better search than Google (which is ridiculous). I still have to search on Google if I want quality search result instead of StackOverflow. With more power comes more…
We use that license because it protects the content from us. No matter who comes along to run Stack Overflow in the future, Stack Overflow can't do something like put up a paywall and lock it up. Someone else'll just be able to host a copy.

#15I don't understand why Google can't figure it out and remove these clones. They can do much harder things. Why couldn't them outrank sites based on equal text content or -- much better -- huge presence of ads.

I don't think so. Those sites redisplay SO content, but they're not linking to SO. They're actually trying to out-rank them, up their own traffic, and drive up their ad revenue.

#17Google doesn't have a good way to establish provenance, and has trouble distinguishing copies from originals. It's a common complaint of blog operators that some bigger blog copied their stuff and got a higher ranking on Google.

Since establishing provenance is such a big problem for Google, perhaps it might be a good idea for Google to offer a time-stamping service itself?
