Yeah they can see who reps them, along with a lot of other features.
Lifetime membership comes with ability to see neg reps, a hidden secrent form that only lifetime members can go to/see, inside it are cool things like shoutbox and other neat features, as well as the ability to use sigs, etc.
It's worth the $10 if you are wondering.
