In a way, yes, it is good. Why? It prevents people from getting out of line. It doesn't matter if you had a strike or two, years ago. SE takes these things a little serious which is good. Would you rather them take the strikes away so these individuals can act out of line again and accumulate another 2 strikes off the bat? It's good to leave it as it is so they don't act out of line. I don't care if people make "Mistakes" or had a bad day. Those who do have strikes are "Scared" to talk openly probably because they can't say anything at all without sounding like a donkey. Just don't be rude at all and keep things simple.
