I use RemoteSign extensively around my layout to provide arrival and departures signs, platform signs, etc. Some computer algorithm on a big social media site has however decided that the RemoteSign web site contravenes their policies, making it impossible to share a link to the site on FB.
You can instead link to this page
which is: https://cabin-layout.mixmox.com/p/remo.html
and from here, people can follow these links to the RemoteSign web site:
Main site: https://remotesign.mixmox.com/
RemoteSign Sequencer: https://remotesign.mixmox.com/p/remotesign-sequencer.html
Latest news: https://remotesign.mixmox.com/p/latest.html
Live German station data: https://remotesign.mixmox.com/p/db.html
It may also help to submit a protest to FB if linking to RemoteSign fails.
