Is there time for a service that looks at any README on a github project or other indexable repos, and give it a cute landing page and failing grade if the install recommends curl http://supersecure.script - | bash # fuck my box.
Perhaps ismyboxvaklem.pt?
As a warning, it actually is dangerous to run, but it conveys the point succinctly.
otoh, don't you think that without the unsecure one liner to install it, some people would complain about its lack ? Stating they can read the script before executing it anyway.
Plus, it's not much less secure than cloning a repo and running 'make install' (in both case, one could read the script(s) but will unlikely do so).
$ curl http://supersecure.script -O foo.sh
$ bash foo.sh
