nabla: I'd tend to agree that a bot should be clearly labelled as a bot. At Fibs it's not always clear but, as there's a clearly established bot ethos, it doesn't really matter too much, especially as there's a full range of abilities exhibited by them. "Bot" doesn't mean perfect by any means.
As for tournaments, well, you know my interest in getting DG "bot standardised", but here, where the rating system is *ahem*, there is no value in that. Even if there were, tournaments wouldn't be ideal anyway as the players are self-selected and so uniformity of the pool is absent. And so I'd agree that there's no need for it to play tournaments. I'd almost suggest that a bot should only play unrated except that people could have fun playing one-pointers against it and sucking points out of it! ;-)
