I've name changed for this as I know quite a few people in my town are mumsnetters.
My friend who I've been close friends with for over 20 years is very opinionated, particularly on social media, which often lands her into hot water and spats on the internet. It's been so bad the past year that her youngest daughter is being bullied at school because of the way her mother behaves on Facebook. I've tried time and time again to advise her but she just doesn't listen - thinks she's invincible.
Anyway, we have this local town Facebook group which local people air their views etc. There has been a new member of the group join that is quite obviously a troll. Says disgusting things - really disgusting things - about local people, slandering them etc. The worst was they did a post about a disabled person making fun of them. This has been going on for months.
I was round my friends house last night and was having trouble with my online banking app on my phone so asked to borrow her tablet so I could log on and move some money. As I was logging on - a message popped up on the messenger bit and I could see from the first couple of lines it was abusive. Without thinking I opened it and quickly realised that my friend was in fact the troll on a fake account, and this message was from a local person being abusive about a post that's she had recently posted.
I didn't say anything and just handed the tablet back after I finished, marking the message as unread. It's playing on my mind - do I confront her? Do I out her?
