Not accurate!
1. They either don't know the meaning of what the word means
2. They simply neglect and go ahead posting without reference to the source or three, they just don't know the rule.
3. They don't know what to post but really need to keep up with activities
4. They don't know the rules and regulations of the forum.
1. If they don't understand the word meaning, why they make post? It is time for them to learn English and use the forum in Read-mode only.
2. If they don't know the rule or know it but ignore it, they deserve the ban.
3. If they need to keep up activities (or post quota) but don't have ideas to use, the forum is not for them.
4. It is the same as the 2nd point.
Plagiarism evasion = rephrase + source = OP = Active
Posters don't need to rephrase to be active. They can do terrible rephrase and wipe out the good original meaning.
You can copy, paste, with links and show up your own opinion. No need to rephrase with links without your own opinion.
