It means that plagiarism is not only for newbie but to high rank users too. Ban for plagiarism has no exemption in rank. But OP focuses that much on newbie which usually does plagiarism because of thoughts that no one is checking on them because they are still newbie. Besides they too forgot to read all the forum rules and regulations. Not only the forum rules and regulations are important to read but other pinned post too. The problem is that newbie has no patience in reading posts and they thought of it as alright to be here and they are good to go.
As days pass since newbie could have hard time participating in the discussion they tend to do a quick google search and for them not to encode it manually copy and pasting is much more easier. Now, if the copy paste post will be reported surely it will resulted to ban especially if reference were not being mention.
