Speaking as owner on Zowex.com here - there will be very, very few 5* websites.

I've put up a system which scans the uniqueness of DDLs submitted per site, and 85%+ of websites submit the same material.

This, the site design, the site speed, how much mature is the website, which ads are used, the links used, the format of the posts and many other factors will make it hard to get 5* on Zowex thus completely worth it.

Currently all sites are 1*, but we send nice hits
