Unfortunately xybot isn't sentient, because otherwise, in the words of General Dreedle, we could take him out and shoot him.
xybot has not announced his presence on talk-gb, yet 'he' has taken it on himself, without consultation, to change "denomination=Church of England" to "denomination=church_of_england" here (and doubtless elsewhere). This similarly. Nor has he announced himself on talk-ie, yet this.
And what, pray, is this all about? User xybot, but created_by=Potlatch 0.11b? The bot knows how to work Potlatch? Blimey.
It is so, so tempting to write a xyrevertbot. If you see an automated user called General Dreedle you'll know I've succumbed.
