do you mean that for example the tripadvisor website is
often more up-to-date for a POI than the POI website itself ?
AND that tripadvisor website is not enough to have all contact info and 
it is why you need to add several thematic website to have all contact ?
if yes, please feel free to give an example of official website of a poi 
and many other website needed to have updated contact info
my experience is the opposite: seo pollution is sometimes so important 
that it is difficult to find the "official" website of the poi that 
contains the updated info, while other sites sometimes have very old 
information.

another problem is the quantity: should each thematic website
add its url to each of the poi of which it speaks ?
it is potentially a lot of tag for each poi ...
by exaggerating, all the results of a google search will end up
being added in osm, with no added value for the osm data user.

it might be useful to have an id to be able to link to these reviews, 
but this has nothing more to do with contact:*, it would need a 
dedicated namespace like review:* and a proposal to have a system 
harmonized and usable at the global level, instead of every mapper
doing what he thinks best.
and maybe it makes sense only for review system where you can retrieve 
the note from an id. systems where you have to go to their own website 
are unusable from an osm search (find a hotel close by with a 4 star review)
