I do confirm that i explicitly tested this with my super unused facebook account, just stating that i was testing restrictions on talking about Linux, the text was: """I don't often (or ever) post anything on Facebook, but when I do, it's to check if they really, as announced on hckrnews, are restricting discussing Linux. So here's a few links to trigger that: https://www.qubes-os.org/downloads/ ... https://www.debian.org/releases/stable/""" and indeed within seconds I got the following warning: """ We removed your post The post may use misleading links or content to trick people to visit, or stay on, a website. """. This is one massive wow considering how much Facebook runs on Linux.
