Projects with inactive demo sites

[LuquiAD]

While trying out the side, I have spotted several projects, that have inactive demo sites, yet the GitHub sites hosting the code are still up, yet seemingly haven't been updated in a while.

I have already begun removing them in the work, yet I find the situation slightly ambiguous, as some people might still want to be able to locate the source code on GitHub easily, so I would just like to double check with you, if those projects should be removed.
