Unfortunately, you'll go from titles of "hash" and "Hi" to "hash problem" and "Hi there". Is that progress?
An idea I've had very little time to reflect on is that PM could run a search on the proposed title, and if it gets too many hits, reject it with that reason (title is too generic). Of course, we could still get "hash 12345" then, but I think it at least addresses the problem directly. Admittedly, it's not likely as easy as ensuring that the title meet some pattern.
