I have spiked every day since I started playing 2 years ago and have yet to get warned. I've played in tournies cws and events but no one seemed to give a shit anyway. Besides the playerbase is too small if you think they can afford to warn anyone, I mean their *permabanned* players literally just come back every 6 months between *permabans*.
Advice: deal with it and move on because nothing is gonna change
