It's up to the community to police the content, domains are now clickable and have a submission history page just like users. It only takes one person to notice exploitative behavior for the community or moderators to intervene. I think it's getting better though, it seems like plenty of startups can artificially hit the front page a few times but once the voting ring filter's got all their employees and friends it is much harder.
