I have been trying to give polite suggestions to people to point out things that they say or do that could be seen as breaking JU's rules. It's funny, some are quite nice and say "I didn't know I did that" while others fight it tooth and nail.
If your boss came up to you and said: "The 3rd graph in this report is done wrong. Please make sure that next weeks report is done correctly." How would you react? Would you say: "Wow, I'm sorry. I will work on that." Or, will you fight with the boss and say: "It's my right to do it this way!" And, please realize that even though that graph may be better than the ones you previously did wrong, it doesn't mean that it's still not wrong. Don't expect your boss to dig up the worst case and only comment on that one.
The admins on this site mention things only to try and help you. Otherwise, they could just wait until your actions are so egregious that they just ban you. Which makes more sense? I would hope that sooner or later people would realize that the admins are just trying to make this a nice place for everyone. Their job is no different than the peace officers, in that they have to help people see their mistakes and resolve them so that the other citizens don't get harmed.
If an admin says something, don't fight it. You don't have to respond at all if you don't want to. But, admins are only saying things to help. If all we get is backlash for that help, we will just quit saying things since it's not worth the grief.
