Re: X-T&C header
"** I admit to being one of the few who I know who does read T&Cs and frequently refuse to accept and thus not use some web site."
The problem is the site owners have no idea that you made that decision. There's no way to actively reject the T&Cs, just the passive method of not re-visiting the site. Rather similar to Facebooks "like" button and lack of "dis-like" button.
