Because of the fact that they are different sets of people, and because of the fact that doing name enforcement requires already having a complaint filed. Unless you're suggesting that names enforcement people will look at the separate feedback stream (when they're supposed to be busy working on complaints), go look up profiles, file complaints against them, and then mark the profiles suspended. I very much doubt people will be that malicious and motivated.

I suppose it's a risk, but it's not that big a risk IMHO.
