What measures do you have to prevent a candidate and their reference from collaborating and sharing information resulting in the linkedin status quo? Why can't I just say to a reference to give me access to their searchlight account and write my own? Why can't I say to somebody "Hey, I'll write my endorsement, you can write yours, and we will post eachothers endorsements on our own account"

Furthermore how do you distinguish between a high quality endorser giving accurate information about candidates and a low-quality endorser trading favors to bolster their own number of endorsements? Currently on linkedin I can see somebodies endorsements which can raise red flags about them "trading favors". How will searchlight provide a similar ability to scrutinize endorsers?
