I'm not sure about this.

One thing, is this feels like an escalating gesture, i.e. communicate anger. The trouble with anger is that it's contagious. Quite often the recipient just gets angry back, and so it makes the situation worse. What we want, is to make the situation better

patchwork@2 had flags, and they came in 2 flavors. "abusive" or "spam". This was also escalating, "abuse" is a very strong word, and this meant that someone got flagged as abuse but really didn't feel like he was being abusive. where as he could have hardly denied being "annoying". Another time, @johnny was writing a bot, but it had a few bugs, and these extra posts where flagged as "spam", but that was hurtful, because "spam" is intentional, but it was just an accident. maybe flagging as "oops" would have been better.

I'd lean towards communicating sadness instead of anger. There is lots of ways a sad button could be used. If you loose your kitten - definitely sad. But sometimes you do something, and later it makes you sad. Maybe you said something unkind, or maybe what you tried to say didn't land right. You can still apologise for things you didn't intend to do. I think the world would be a better place if people said "sorry" a bit more often. So, you could click sorry on your own message if you regretted it.

hmm: is there a lot more nuance in the ways we express negative emotions than positive ones?
