Yeah, it should be clearly visible. E-books bought from certain shops come with a notice like “This copy was bought by Tiuku” on the first page (and probably they have something like this embedded as well). When it’s done in the open like this, I think it’s a pretty fair way of doing DRM.
Is it ‚really‘ fair, though?
When I buy a physical book, I can borrow it to others or resell it as I please without ever really having to reveal Information about myself. Why must a digital copy of the same book be forever branded with my name/account info?
