A removed and nonactive third-party Kodi repository has become vulnerable after an outsider re-registered the GitHub account of its developer. Former Kodi-addon developer MetalKettle urges people to delete his repository, stating that it's no longer safe.

Worried about potential legal risks, he saw no other option than to halt all development of third-party Kodi addons.
Two months before this announcement, the developer proceeded to remove the GitHub account which was used to distribute his addons. However, he didn’t realize that this might not have been the best decision.
As it turns out, GitHub allows outsiders to re-register names of deleted accounts. While this might not be a problem in most cases, it can be disastrous when the accounts are connected to Kodi add-ons that are constantly pinging for new updates.
In essence, it means that the person who registered the Github account can load content onto the boxes of people who still have the MetalKettle repo installed. Quite a dangerous prospect, something MetalKettle realizes as well.

“Warning : if any users have a metalkettle repo installed on their systems or within a build – please delete ASAP,” he added.
