I'm both venting and guessing a little here, but a business phone number of mine recently started getting calls for a dissolved, and not previously heard of, business. I think it goes like this: Business sets website up in 2013, showing phone number. Business website attracts some links (nothing major, 100 odd). Business closes, domain drops, telephone number recycled to my business. Domain registered in Mar 2016 (on the drop possibly) by SEO guru. Old website rebuilt from Archive.org, and displays telephone number. I start getting calls for old business! There is only one outgoing link on the website. It is to a website named, wait for it..
