I'd be slightly averse to it based on the fact that, in matchmaking service, people are actively looking for relationships and so they might give a false or exaggerated impression of themselves in order to seem more desirable. I'd be more worried that the person would turn out to be very different from how they seemed initially.
I'd rather go for someone who I would have met a few times at first, when neither of us were even thinking about the possibility of a relationship with each other, and therefore wouldn't have felt the need to put up that facade (e.g. people met through mutual friends or family).
