That is because most of the people who plagiarise do not know it is against forum law. They act like it is the regular classroom cheating where students copy each other and submit without getting caught for malpractice. But this place is different and people pay heavily for that when caught in the net. Members have to acquit themselves with the laws here so they do not act that way and get punished for it. I have pity on op and let us hope he gets a second chance on this.
i don't know what will happen to this forum if hard rules don't apply to members who commit plagiarism. Is it that complicated to make up an own words? those who want to work hard to improve their literacy skills will definitely never have the intention to commit plagiarism because that is a form of appreciation for the author of the writing. to OP, i hope you can learn from this incident, good luck with your appeal.
