The fact that five people have found the review helpful is rather deceptive. It all relates to the weird and not so wonderful way that the TA review system works.
If you look further, all the comments on his review actually give it a score of one out of five in terms of helpfulness, so I presume may be some of you had hoped to show your disapproval of what he said by giving him a low score. As there is no way of giving a negative score, so everybody's comment on a review is recorded as helpful or positive. (I hope that makes sense, I haven't had enough coffee yet)
So, unfortunately, on first glance this just shows that five people found it helpful (albeit not much)rather than inaccurate or incorrect.
There used to be a way of registering a negative opinion of a review but that has been removed by TA. So that is openess and fairness for you. Under these circumstances it seems quite inappropriate for him to criticise CBF.
The only way to counter it is to write another review or use the 'report problem with review' button.
