Ask HN: Are you comfortable with Checkster's User Agreement?

A friend of mine recently started the application process for an in-house software development job at a firm where he was formerly working as a contractor. The HR department instructed him to use Checkster, but he found that service's User Agreement to be alarmingly broad. Unfortunately, when he indicated to HR that he preferred to submit his list of references in a more conventional manner (and explained why), he was told he must agree to use Checkster in order to apply for the position. I reviewed the User Agreement in question, and I too found it to be a bit troubling: https://app.checkster.com/legalese.php Essentially, it seems to waive one's rights to fend off defamation, slander and libel, and to relieve Checkster of any and all legal responsibility in the event one's reputation were to be genuinely abused via their service. What does HN's readership think of this User Agreement? Have you encountered others like it? Have you been in a situation like my friend's, where refusal to make use of a 3rd party "HR service" has proved an obstacle to being hired?
