I once messaged someone "I thought you were nice..." when they acted nice at first and then stabbed me in the back. It was a quite a few years ago, I was pretty young and got frustrated so I sent them this message. They reported it and I was silenced for a "I thought you were nice" message. It didn't have anything else, no insults or whatever, but I still got silenced.

It still bothers me to this day. x_x
