If I set terms of service for my web site, visitors to my web site agree to them when they use my web site (beyond, presumably, the usage technically required to obtain the text of the terms).
It is not unheard of for web sites to charge users to access them. Usually this is implemented as a paywall, where the site refuses to provide pages until the user makes a payment. But that creates friction on the customer journey, because the visitor has to bother with advance payment.
Can I declare in my web site's terms of service that accessing my web site costs money, and then seek to collect from repeated visitors? Is there some threshold of noticability that that term would need to reach to actually be binding, since it would be highly unusual?
If I somehow could identify a frequent visitor who hadn't paid, and sent an invoice, would I get in trouble for some kind of speculative invoicing crime?
Would I win a debt collection suit against them if they refused to pay the invoice?
Would I be able to compel an ISP to reveal the identity of a subscriber in order to collect a debt from them?
