Wait, they've not merely copied his js, they're having him host it too? Oh exploitable. Figure out to make it benefit you. I'd have a hard time resisting the urge to play some mischief though.

No, at least the one I looked at didn't. But if they're just copy-pasting, he could add a domain check (or IP address check) and make it behave differently.

Edit: apparently some of them are! https://news.ycombinator.com/item?id=5165238

I'm generally against all forms of intentional defamation, but I must admit that this option is very tempting...

Are there any lawyers here that could weigh in on the legality of this?

And I would be especially interested in this site: http://www.creativegerms.com/about

I don't see any similarity at all (except for maybe some basic stuff that can be found on many websites) and including them into that "ripping off" article could be perceived as defamation. Did they just quickly switched to different design?

That one was a bit odd in my mind, too. Maybe it re-uses some code or something?

I can't find a cached version of it anywhere that shows what it looked like an hour or so ago
