Sitewide links are not likely to hurt you. Most of the time when people complain about it hurting them, it usually comes down to those ROS links stopped helping them when they stopped getting credit.

I do think that a large quantity of less-than-trustworty links can do you some harm, but only if you have very few trustworthy links.
