I'd been in facebook since 2006 and so was a member of a great many groups... but increasingly the content of group posts were subject to censorship,
often by autonomous AI bots... which seem to have perfected the art of getting the wrong end of the stick.
A perfectly innocent post results in a ban. The poster then finds themselves in a position of having to try to appeal after the event, without any clear
understanding of the offence and without any knowledge of who they are meant to appeal too. Most times the appeal, such as it was, would either be ignored
or dismissed.
