She can ask for it to be removed but it actually brings some quality traffic
Then I'd keep some links, but maybe not run of site - you could ask the owner to back off a bit. Maybe go with just the home page, or whatever pages are sending the best traffic.
However the fact that there are only 5 other backlinks is more the problem IMO, not the one case of ROS. Surely if the site is worth ranking, then other backlinks are possible.
