"Text laundering" fools plagiarism detection software

From How To Fool A Plagiarism Detector



All a hypothetical plagiarist needs to do, to evade such software, is to make sure that no more than, say, any given three or four consecutive words are identical to their source. So they can copy and paste, so long as they, let’s say, change the word order a bit, add or remove some filler words like ‘the’, ‘and’, ‘but’, and replace a few words with synonyms. I call this text laundering.
