False reports

Once again receive a warning because my behaviour hasn't been in line with the summoners code. I've been reported for offensive language. Which is pretty funny because I haven't been talking in my games. I said one thing in my last game that wasn't "gj" or "ty," and that was "The magic touch." in teamchat, not even all-chat. It's honestly frustrating getting these, because then someone will pop up here and say, they only send the warning when it's validated. That's not true. I haven't even addressed my teammates recently, much less said something offensive. It leads me to believe I'm being falsely reported by the enemy team, because I don't flame, afk, feed, or do anything that's in any way remotely out of line with the summoners code. So the question remains. Do they send these after being reported, or after they're "validated?"
