Plagiarism, especially those in the online realm, is now incredibly easy to catch. With plenty of tools that can spot copied, repurposed or coopted text, attempting to plagiarize other people's material can be an exercise in nothing but getting caught red-handed.

With that said, it's always prudent to check everything you write to make sure you don't end up plagiarizing other people's materials accidentally. There are, of course, a few precautions you can take when going through your writing projects to make sure you're not stealing anyone else's work.
