Some of the people who are still active on the forums were part of the reason it was removed to begin with. One of the biggest offenders of reaction abuse is still here, I’m sure they’ll comment soon. There was a reason it was removed, why would that reason no longer be valid?
Insulting other players is literally against the skyblock code of conduct. Why would they add a reaction to encourage that?
How does reacting dumb help in anyway? You can agree or disagree, like or dislike. Why do you need something that is quite often used in a rude way. When responding to someone’s opinion or question you can make a statement, but reacting “dumb” adds nothing to the conversation and is more often than not used to insult a person than disagree with a comment.
