The reviewer can decide if a report is open or limited. It is up to them if they use it. But perhaps it is against the purpose of the forum.
Still - trolls and lurkers and touts are irritating.
the reviewer can share when they feel the need or as smiths says when he has had his fill, you already have that power to withhold already.
Everybody is a troll to somebody, an overused word IMO.
Luker is better than someone posting shit to get access to the reviews
Touts will always try to get a free advert on a successful site in any field, joy of being in the internet.
Site is successful why change things?
