This is one of my problems with the current system. I think if people leave a negative response they should stand behind it. There was a thread some time ago that attracted a lot of negative emojis and at one point it felt a bit like people were piling on sarcastic ‘responses’ because it was semi-anonymous. (Even on a computer I find it difficult to see who’s reacted when there are multiple ones with the current system.) I don’t think it’s very healthy for the forum and the level of discourse. If it were me I would actually remove the negative emojis from the available responses. IMO they never improve the conversation (even when I agree with the sentiment).
Edit: @ddmiller this is where you can add a load of negative emojis to my post while the current system is still in place
