do the websites have a common footprint? eg. are they built in the same style, are filenames similiar, is the structure of the site similiar, do they have the same js names or css names, is the code laid out in the same way? do they have affiliate links with the same aff id?
do they link to each other?
there are so many ways of telling, an unsophisticated user can't tell but as users have more experience and/or data patterns to go on (such as search engines) then they can tell very easily.
although I think some redirects will end up showing at the wrong location.
