I am a man and a man can make mistakes. But they talk like they've never done anything wrong in their whole life. I've told them many times that I apologize if I make a mistake. But they continue to attack me.
How many times a man could repeat same mistakes? You should know what is the mistake and definition of mistake exactly. 
You are apologising and on the other hand your title say they are abusing power. Can you explain it if you done multiple crime and judge send you jail then will you say that judge/police abuse their power? How could you expect that someone will excuse instantly after apologies? When you have done mistakes then you should change posting behaviour before make appeals or apologies. By wrong blame, you just drawn attention from more DT members and getting more tag.
Actually this is the result of quick merit scheme. You have chosen a shady way to earn merit quickly which is really punishable in my opinion. You should not create arguments if you are really not legit. You know very well what you have done. If I were you, then I would first change my posting behaviour instead of blame to DT members. This isn't right way to apologies, your thread and title conflicts each other.
