Facebook Censored Me For Mentioning Open-Source Social Network Mastodon
I doubt anyone at Facebook is freaking out about Mastodon and setting out to censor all mention of it.  It's probably just a keyword or link that tends to co-appear with other, actually rule-breaking content, and some automated system has learned to block it.<p>Still, it does seem like the sort of thing that could get Facebook in trouble with a regulator if you squint at it.
