Multiple reviews via REST API

Hi all,

we're currently working with Reviews via REST API.

What I found out, when playing around with the API is, that you can submit multiple Reviews on one product.

1. Submit review

/restapi/vc/products/id/{product_id}/discussion/reply

2. Review (Message) object gets created and all existing Reviews get updated with this new rating value

I don't really think this is the expected behaviour, since ActiveCast is blocking this action.

Am I supposed to actively block a second review by a user by checking if he already submitted a review on this product yet?

Thanks for your help!
