Ask HN: Dealing with a website rip-off in 2016?

I saw some referral traffic today from a site that is trying to clone ours, even so far as replacing our company's name in screenshots of our website. It looks like they're located in the same state as us (California). Has this happened to you? What course of action is recommended for this sort of thing these days? It doesn't really seem worth talking to a lawyer about as it's not like they're taking any traffic away from us or have really built out any of our software, it just feels really slimy. I guess my current thought is just to ignore it, but I thought I'd also ask if anyone else has dealt with this kind of thing.
