I have to admit, there are a couple of times in a few games when I "sorted out" a few players. But only when I was 100% sure they were malicious, and tipped me over the edge. And almost all of the time I just don't get involved in that stuff.
There's a big, glaring problem with applying the principle of revenge. A certain percentage of the time, what seemed like deliberate contact may just have been accidental, or even just careless.
In a race a few days ago at Interlagos, I was on the inside of another player. He turned in and his rear wheels caught my front wheels and it spun him off. It was clearly not my fault; just his lack of awareness. A few laps later he got behind me and completely rammed me off.
I let that one go.
In the next race at Spa, I got a puncture. Going up the Kemmel straight, I just pulled to the side slightly lifting off, letting people pass. As the same guy was passing me, in the middle of that straight, he turned in on me and wrecked my car.
So from his point of view, he was getting his own back on me for spinning him in the previous race, even though I didn't spin him in the previous race...but he didn't know that. There are far to many 1-minded punters. But there are also far too many people who are too quick to blame others without being sure of what happened.
I always race cleanly, yet now that I think of it, so many times I get rammed by someone due to a misunderstanding (primarily lack of awareness of other drivers).
