The VEL team have introduced a new listing category for abandon ware, while not always vulnerable to exploits, projects abandoned may in time introduce an entry to exploit websites.

Reporting is easy and consists of a few simple questions. Your Name & Your Email, so we can thank you for your report,  obviously the extension name,  Extension url so we can check it out and also reason you believe its abandoned.View the abandoned list at https://vel.joomla.org/abandonware and report them via the abandon ware form
