Some automated bot added an extra PHP file and a redirect, so when Googling for this website you would have been redirected to a page selling drugs.
I’m still trying to think why looking for some Fedora package would trigger a compulsive Viagra purchase, but hey, not everyone is the same.
Page & redirects have been removed, everything is back to normal. The specific repository pages were not visible (404) due to a faulty WordPress plugin update, which I removed. A crawl from Google has been triggered to remove the drugs page from Google search.
I will move the GPG public key of the repositories somewhere else, so people can still check if they have any doubt.
Now, If I could figure out how to remove that Jetpack error about AMP….
Also, looking for a cheap hosting solution (hey, this has been running for free since 2013), ideally where I also manage the website (no more WordPress..) and not the hosting company managing it for me, so if you have any suggestion let me know.
