DISU

Social news aggregation and web content discussion app, such as text posts, links and images. (video comming soon).

The app is available only in english, but it supports many languages.

Users are only identified by just a number, no passwords, no emails, no registrations... just a number generated when the user opens the app for the first time. Although the users are anonymous, they have karma.
Users start with 5 points, and earn karma when other users (up)vote in their posts. They can also lose karma when other users report them because they find something innapropiate. When a user reports about something, this user will lose 1 karma point, and the reported user will lose 1/3 of the reporter user karma. When the karma goes below zero, the user is banned. The user cannot post or comment anything until the ban is gone. The ban times increase exponentially each time.

Users can send private messages among them. Receive notification when a new message arrives is optional.

Also the users can quote comments form other users, and the quoted user receives a notification. The notification is also optional.

Users can see the best posts of all users in different time ranges.

A favourite post list is provided, so users can save (and remove) the posts they find interesting and want to keep record.

It is possible to close the access to the posts to only vip users. When creating a post, it can be selectable the VIP access. Only users with vip access can see these posts. The only way to obtain VIP access is using a invitation code inside the app. When a user becomes a VIP, 10 points are added to their karma.
