I can imagine a competitor trying to boot you off by bombarding their abuse team with bogus complaints and triggering automated actions. It's been done in the past, the problem is that all major companies (not just hosting, but ANY large company!) try to save on actual customer support and even more on stuff they can't bill to the customer, like a properly staffed abuse team.
