I’m always confused as to why so many websites from the US don’t provide some sort of physical address, a name, a telephone number, even only a email address. Maybe I’m spoilt because it’s actually against the law in Germany to not provide name, address, telephone number and email address on your website (you can either put it on every page or put a link to the page with this information on every page) but to me it just seems impolite, unprofessional, even scammy if you don’t.
