Of course it should be allowed, especially since the OP did not hide and made it explicit that the text was written by an IA. I can't imagine on what grounds such posts could be censored here when they are allowed all over the internet.
Just because something is allowed in other places doesn't mean that it should be allowed too here as well. Take for example stance that this forum his on plagiarism, compared to all the other forums. And yeah, that post should be dealt in the same way mindless copy/paste is (mp matter the source link), meaning deletion.
It seems that the shitposters in the Gambling board don't mind it at all, and the OP was even awarded with a merit - the post has been reported, we are waiting for the decision of the mods.
An average post quality in that board is so low that the post in question is above average one and every new topic is seen as an opportunity to fill signature quota. Not that situation is much better in other parts of the forum, but there is the most obvious.
