A user who copied a few lines into 95% of his own words and forgot to reference the few lines he copied is not the same as someone who wrote a wall of copied text; both are plagiarism, but I would personally PM the first user and tell him to properly cite his work for the sake of the 5% plagiarism rule then report the other user for plagiarism.
There is no time limit. If you believe it is deliberate plagiarism, you should report it; however, if you believe the user forgot out of stupidity to include reference links, a simple PM can remedy the situation.
That means is not sure before taking decision and is under assumptions, because i think some people don't fall the victim of plagarism intensionally, except it's the person method of life is to mimic someone kind of research, i think the best is to pm the user base on the rank, and if happened to be old user it's very obvious that such Skip the memory and it deserve to be corrected through private information or communication, so if the user refused to accept it's mistake within some hours, the function to report to the mod can be carried out without hesitation and that indicates intensionally Plagiarism instead of unintentional mistake.
