Also, I don't think it is as big of a problem in terms in the number of people getting into trouble doing this.
It's become worse in the last few weeks since the change to the merit system. Shitposters suddenly find themselves in the need of a single merit, but they don't know anything except shitposting. Instead of spending 5 minutes to read a thread and formulate a coherent reply, they generally are just resorting to plagiarism +/- text spinning. We have even seen some legendary members selling a couple of paragraphs of plagiarism to one-line shitposting newbies, who will post them, and then receive a merit from the legendary.
Edit:Well it shouldn't have to be but it really does need to be pointed out that this isn't acceptable
From a thread on Meta earlier today:
Yes, I know that I was banned for plagiarism, but I saw plagiarism from other users and felt that it was allowed on the forum.
