Actually some forum users is taking the forum for granted since the measure of plagiarism actions is not seem to be effective any longer, now people is using another means to violates the rules, editing post after you have be caught for plagiarism does not grant you not to face the implications or stipulates that you did not plagiarised article, except moderators want to consider the factor they have added source of the author after claiming authorship, from my perspective anyone that's caught for plagiarism and at the period of been caught the user began to edit and add source, let the user face the penalty of plagiarism, it's absolutely wrong and  if an adequate measure is not taken it will create a means to plagarise and edit when caught and definitely it will become norms of the forum.
