Not ours.
It's from somebody stepping in when @mediaateam said they won't do Fabrik 4 and @henk started to develop.
He grabbed the public Fabrik 4 pre-release and created the website, but didn't ask.
It was one reason why we moved the repo to private at some point before setting up transition with Robbie etc.
I think it's pretty outdated (based on delta or zeta) but no malware.
