You haven't, but I have. Not often, but it is very annoying when your friends' comments get shunted out of the chat box before you can even fully read them because someone is spamming the same emote over and over again. And yes I do have a chat tab with the emotes turned off and I do switch to it on occasion, but then of course I miss emotes my friends are doing. It's not ideal.
Freedom of expression is about being arrested by the government for saying stuff. It has no bearing on this case, which is about wanting to stop people from being obnoxious in an online chat.
