Every rejection is painful, so I can understand why someone may feel offended. Heck, I don't like having my abuse reports rejected either. 
But I also don't understand the "sooooooo offended" part, much less why people feel it's a good idea to post about it on SCN and, on top of that, accuse the moderators of rudeness when it's not even the case.
One can only guess that such situation occurs because people like me already encountered their share of rejections by the time they finished high school, so we have certain immunity. Now here comes the generation raised by the helicopter parents and teachers who were only allowed to grade their work in smiley faces. No wonder they have a hissy fit when their unrealistic expectations meet reality.
While I do agree with the "yet" part at least in some cases, we can't be patient indefinitely. I'd say that 1-2 warnings should be more than enough for someone who is simply misguided. If behavior continues, then clearly more strict measures are needed. SCN can't play a foster parent forever, people need to grow up.
