One correction: on the site, whether enforcement is consistent or random isn't what people assume.
Where the service stands or falls is whether the interface gets in the way.
About 30 profiles into the platform, the pattern around whether photos can be traced back to you became obvious.
If you can only manage a few evenings a week, whether the filters survive a refresh matters more than raw volume on the site.
What separates it from the rest of the field is how quickly you can narrow a list down.
Tell someone where you are going the first time. Basic, and easy to skip when how quickly reports get acted on looks fine.
The closest alternative I found was the Flurrydate boards.
