Is indexing and aggregating job postings from employeers career pages legal?

I experienced something like this 7-8 years ago. We had an employment link on our web site, identifying that we were open to lateral hires and the qualifications needed for a lateral hire. Then we started receiving communications from folks who had found the add on a job listing aggregation site, one focused on legal jobs. I have never looked into whether copying and reposting these job listings is legal. Copyright protection requires a work with a modicum of creativity. The brevity and functionality of most job postings should not meet that criteria, although the bar has been set so low that it has been debated whether phonebook listings have a modicum of creativity. All I can offer here is that it is a debatable issue. More to the point, I think the question becomes, "what is the harm?" To get statutory damages, someone will need to have registered their copyright with the Copyright Office (only discussing US law here) within 3 months of the job posting. Someone who is aware of your site and wants to stop you, could post a creative job ad, wait for you to copy it, and register it in a timely manner to pursue an infringement action against you that could be worth 4-5 figures (my guesstimate, not the limit of the law). You may also have a fair use defense, as the posting is factually and not intended to compete with the job offeror. But why? Anyone posting an ad is trying to get it distributed to individuals looking for employment. Your site would promote their interests. Litigation is a hassle. If no one takes offense, then you'd be safe. If someone does take offense and you immediately take down their ad and promise not to post their ads in the future, they would likely be satisfied. I can't give you legal advice or legal conclusions because I haven't looked at the issue on point, but these are my thoughts on the subject.
