Please add support to Google Product Reviews for is_spam YES or NO
Defaults to NO
Google and other aggregators no longer like to have none consequetive review data, meaning review uploads should look like 1,2,3,4,5 and not 1,2,4,5 (3 missing) where review 3 was a SPAM item.
See is_spam fields in the specification
This way we can export all reviews 1,2,3,4,5 where 3 is marked as is_spam = true
