I don't think so that if a member is aware about the consequences of plagiarism and knows in advance that if found guilty the account will be banned he/she will not be lazy to simply copy paste the article and wait for the account suspension afterwards.What will the fun of it as you won't get anything but will surely loose your account.Newbies can make such mistakes if they are not aware about forum rules but laziness i can't say fit this matter.You cant be lazy enough intentionally to make such mistakes.Just my understanding but if you have come across any such case then it's different matter.
