I should have been more accurate in the OP.
Agree with all comments about providing full contact details if you have a business (online only or B&M) where YOU actually provide products or services to paying customers.
But there are many online businesses (eg.. affiliate sites) that link a buyer to a merchant who then provides the product or service. It could be argued that there is no need for anything more than an email address somewhere on the affiliate site.
But the OP was really about whether a site is going to get a smack for having no contact details at all.
