If they have signs telling you to have your kids check you in, having an automated tool that you set up yourself do it shouldn't bother them too much.
However, I looked at the FAQ, and for paid accounts the tool hits the check-in constantly looking for a better seat for you. That might tick the airlines off enough to ban the site's IPs.
