What's the difference between this and simply keeping track of how many messages each user sends in a 24 hour period and blocking people who are obviously spamming?
Spammers don't have to appear to be the same person every time, nor do their messages have to be identical or even similar, so blocking of that kind can be worked around fairly easily -- at least more easily than hashcash.
