@Dom Atreides: I don´t think our WPThemeDetector plugin detection feature is any "bad idea" at all (for obvious reasons). For instance, many people use our tool to find out which particular plugin a site is using for a particular functionality, once they´ve seen it working on that site to their satisfaction, so our tool may help them choose the right plugin for that job. Plus, if anyone wanted to search plugins for malicious purposes, they would do it anyway without the help of our tool.

@Havenswift Hosting: When you say that our tool is not very accurate, is it because it showed you any false positive or just because it didn´t detect all the plugins you use? Please bear in mind that not all the plugins are detectable (for example, plugins used for the admin area or for backups won´t show up), and also that not all the detectable plugins will be detected on every page of the analysed site, so the number of detected plugins will depend on the url being checked (for example, a plugin dealing with comments won´t be detected on the homepage of many sites).

In general, our tool is intended to help people choose the right theme or plugin once they´ve seen them working on real sites, not for just snooping around other people´s sites.

Maybe that´s the point Havenswift Hosting is missing.
