I've got an imprint, including my mobile phone number, on my partly personal, partly business website for about 15 years now. In this time I have not received any calls or unwanted mail on this address. Not a single one in all those years.

Maybe your website is not popular enough. I had a website a few years ago (not anymore) and since then I receive about one call per week of "Microsoft" employees asking me to install some backdoor software.

Well, I can't complain about visitors and views and the resulting business out of that. Maybe I'm just very lucky, but it's not such a big deal as OP wants it to be.
