For anyone that considers themselves to lazy to check the url, and verify its the proper one every single time. Then, I suggest that you research it once, and then bookmark making it easier to access next time. Personally, I check the url each time, but I understand others may not have the patience for that.
Very similar modus operandi as the linked Metamask case indeed. Neither of these two cases display any meaningful hits on Google (aside from some reports on scam tracking projects where people report them), so it’s still a wonder how they drive traffic there to scam people. Social Media, Adds and changed links on sites that refer to Metamask are the obvious choices, but alas we do not really know (nor their real impact in quantitative terms).
Although, there's no verifiable way of calculating the real impact. I would say, as long as they're getting this link out there, many will fall for it. Just think, many people still get fooled by the "I'm a Nigerian prince, and I'm going to give you free money" type emails. So, I'd assume something that I would consider more obscure would be successful. Obviously, assuming that they are promoting this to a large enough group.
