Martin Brinkmann, writing at GHacks, targets the proliferation of spam extensions flooding the Mozilla Foundation's Firefox AMO Web Extension Store. Further proof of deep administrative incompetence at Mozilla Foundation, or something else? You be the judge.
"The site is abused by spammers currently who flood it with extension listings designed to get users to click on links in the description. The method that these spammers use is simple: they have copied the Chrome extension Hide My IP and use it as the extension that they upload." - via Martin Brinkmann, writing at GHacks
