Reviews are tied to app store accounts, which are tied to credit cards. Reviews also reset with each version of the app. You could detect the same accounts being used to review each version of the app, discount ratings from newly created accounts, discount ratings from accounts with reused credit cards, etc. It seems like an easier way to game the system would be to pay anyone with an iPhone $5 to download and rate your app.
- potatolicious 12y agoThere's lots you can do to detect "false inputs" like this. How hard this behavior is policed is based on how badly Apple cares about this problem. All evidence points to Apple not really caring about abuse of this variety, so the obfuscation needed to pass any filters are pretty basic.
- bduerst 12y agoThe reviews themselves are near worthless, but in bulk they start to gain value. It would probably be better to cluster reviewers by apps they've reviewed, and to try to find patterns that way.
- titanomachy 12y agoYou can have an app store account without a credit card. I don't think it was always possible, but it is now. Also, the accounts don't have to be newly created. This operation could be quite long-lived. You could have some automated system which loads many different apps to be rated, so that the person in the picture isn't rating the same app over and over again in a short period of time.
