I miss being able to use it, but I'm 100% in favour of it remaining banned. I was a recipient of the nasty sarcastic passive aggressive (😂) and I am a very long time Mumsnet user, kids all grown up, so I know how it can run here. I dreaded to think of how it affected new, more vulnerable, sleep deprived or lonely/struggling with mental health users. Mumsnet originally was set up for new mothers seeking ways to connect to others. Whilst it has greatly expanded in terms of users, that original mission should not be ruined because some users are frankly nasty bullies. On the relationships board in particular, it was absolutely dreadful.
I received it often because my opinion simply was not the trend on a thread. I had a different opposing view that wasn't popular. The whole point of a debate is having discussions with different povs, but some MN users, rather than just stepping back, cannot tolerate the opinions of others, but oh, they wish to appear tolerant in the open, (because I'll give it to MN other long-term mumsnetter's will slap bullying towards other posters down these days) so they are nasty and intimidating secretly. It then feels very personal.
I think sharing that you found something funny is actually nice to share on a thread, better even! Then you can laugh at the laugh. It gathers momentum. It's a group thing.
I'd say bring it back if you have the same relaxed rules as Reddit and Facebook where you can let rip as much as you want in return. But it won't be MN anymore.
The toggle thing. Well if I know I can toggle off maybe that's alright, but a person may not realise it's on, they may have it on naively not thinking that anyone will possibly mock their thread on struggling with domestic violence but being too afraid to leave yet, and just needing a handhold to get through the weekend. Then receive an unwelcome shock. New users might also not know how to negotiate the settings at first.
A long time ago I invited a brand new mum of 4 whose partner had just left her to come join me on Mumsnet for a boost.
First vulnerable post a conceited user attacked her grammar. She never posted again. So I dread to think the harm the laughing emoji was doing.
