Rather than trying to discover if a user is human, focus on the opposite. Look for inhuman actions. The honeypot option is a good initial barrier. But monitor that user's actions from that point on. Are they doing something at super-human speed? Are then repeating themselves a lot? Repeating ones self doesn't just mean the same text exactly, it might mean almost the same text.
Perhaps it is valid for a user to sometimes include a volume of gibberish, but scan all posts for consistent gibberish. These are just a few things you can do to avoid bothering the humans. There are undoubtedly many more and better ways to discover someone as a computer. Above all, take the penalty-box angle on all suspicions of being inhuman. First, 1 min. Then 5. Then 30. Then an hour. Then a day. No need to go longer than a day, really. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
