Snitch is similar to an internet filter in some respects. However, Snitch focuses more on what is actually already present on the computer. This approach to detecting inappropriate materials of an adult, pornographic or obscene nature, is clearly more effective where the web filter has not succeeded in its function and unwanted items have slipped through. It is also necessary for detecting files that have made their way onto the computer via some other channel. In addition, Snitch can detect other types of files, for example MP3 music files, files with obscene filenames, files which have been deliberately renamed to hide their identity and more.

Here is a list of some of the sites that have been of assistance in the creation of Snitch Disk Cleaner software.
