This could be through scam promotions on Bitcointalk, Reddit, or any other social media sites, or maybe through Google ads, etc. Instead of just completely ignoring it, spend a few seconds reporting the scam site as to hopefully prevent potential victims from falling for these scams. Even if the difference to be made probably is just minuscule, it could make a difference.
Remember, it only takes a few seconds.
Thanks! I agree that it's better to do something than nothing. And although I almost never encounter websites which I strongly suspect of scamming people, when I do I don't really know what to do with them. At least making a fast google report is a good start. I got to say, though, that the difference can indeed be minuscule. I report offensive content of Facebook from time to time, and even though sometimes there is very clear hate speech there, Facebook always writes that it does not think this content is against the company's principles (so nobody obviously looks at it, it's an automatic reply). But if many people report the same website, it would probably make a difference.
