Okay, yeah, but it was without malice.
Actually, it can still be malicious. There is no real reason that you needed to do it, and it hardly even helps people because you repeat it right after they say it.
So if they missed the original message, they would still have to page up and see both messages side by side, so it's useless. By that time, they will be shot.
Saying it in deadchat is useless as well.
It also confused people because most administrators thought you were doing it to be annoying. Which is what it looked like.
In other words, nothing good came out of it.
