Because they delete all the bad ones. A lot of their reviews are from people who don’t know they got scammed yet because they’ve never tried to update their tables, or from people who bought a table and updated it before our policy changed at the beginning of 2015 to drop support for pirated tables. The countless bad reviews that have been left on their product listings since then simply get deleted by them. Stupid, right? The review system on the Marketplace is nearly useless because of this.
If you’re wondering how they manage to delete the reviews, it’s very simple. To delete a review, a seller can simply “flag” the review (there’s a link on every review) and mark it as being inappropriate, spam or off-topic. Shortly after, Linden Lab removes it. Sometimes this is a few hours later, sometimes it’s a few days later, but they will remove it. In theory, Linden Lab should be verifying the validity of flagged reviews and removing or not removing them as they see fit. This does not appear to actually be happening. Most likely, the staff behind the Marketplace are overworked and don’t have time to check whether flagged reviews deserved to be flagged, or contained legitimate complaints. As a result, all flagged reviews simply get deleted without question.
