Sketchy

Sketchy is a framework for reducing text-based spam and other malicious user activity on web applications. Sketchy addresses several common issues on web applications:

• Detect when a user submits text that contains spam content.
• Detect when a user submits multiple texts that are nearly identical.
• Rate-limit malicious actions that users perform repeatedly.
• Check user signatures such as IP addresses against external blacklist APIs.
• Collect and consolidate reports of spam from users.

Additionally, you can customize Sketchy to address a broader range of issues.

Sketchy is divided into two projects: the Sketchy core and an example network. Core is an interface for building networks customizable to user actions on a client application, which the example network illustrates.

Documentation

In addition to this README file, there is a directory of additional documentation.

The Getting started guide helps you to understand the example project, which illustrates what a full implementation of the core project might look like. The example project addresses all of the common issues previously listed.

Important: All of the limit or threshold values in the example project are placeholders; SoundCloud does not use these values and recommends that you do not use them.

To contribute to Sketchy there is a Guide to contributing to Sketchy and a list of potential improvements.
