Thanks Gents.
I did have second thoughts about posting this thread, hence why I deleted it immediately after posting. But on further reflection, we can possibly all learn from my experience, especially facebook users. I'm a member of a political discussion forum on facebook and yesterday we were discussing the government's intention to introduce vaccine passports for night club users from September, and it was mentioned that although Labour normally support the government on covid measures, this time they are against it. Given that a sizeable Tory backbench rebellion also seems likely, the government may be defeated on this issue.
I merely said in response to another poster that Starmer may have found a chink in the armour of the government - a commonly used phrase you might think, and certainly employed by me in complete innocence and good faith. But it's landed me with a 3 day ban from facebook for hate speech. At first I wondered what they were on about, but then realised it was the use of the word "chink", which they obviously included in their "algorithm" as a racially abusive term against Chinese people - even though it obviously has an older dictionary meaning.
So the moral is to be ultra careful when posting on facebook and don't use phrases/words which their algorithm can misinterpret. This shows up the limits of robotised moderation.
I've redacted bits of this screenshot for anonymity of me, the group and the poster I was replying to.
