Have you ever been plocked from a thread?

For the first time today I was, & I'm not quite sure why. I'm not sure whether I accidentally answered the wrong post or I offended the custodian of the thread? But in true junkyard dog style, I blocked first & then viciously set upon without even given the opportunity to either apologize or defend myself. Is this just another example of keyboard heroism or simply childish & nasty behavior, or both?
