I got an email notification yesterday about a new posting by 'Ministry of Justice' on nextdoor, being slightly piqued by it and not having logged in for 6 months or so, I logged in to see it was a reminder by the police that in the UK racial hatred posted in a public forum is actionable, and I thought 'yep, that's nextdoor alright'.
A quick look at the local nextdoor posts indeed illustrated a whole slew of 'it's all the <insert slur>'s fault' posts about everything from drunkenness to dog poo on the street.
