I wasn't part of the WhatsApp group personally so this is second hand information that might be wrong, but from what I've heard, from more than one person, there was a girl in the London nobs WhatsApp group who was also a moderator for the nobs Facebook page (who is a WOC) was essentially bullied out of the London nobs chat and there were elements of racism involved. She then also left her 'job' as moderator. I've also deliberately not named her, however if you were even mildly active in the group you'll likely know who I mean
Again, this is a shortened version of what I've been told by various people, this could be incorrect.
