I thing it is just an act of laziness that will make anyone plagiarized on hive when personal thought and experience are more valuable than any other site one can think of.
I have never have the needs to use plagiarism checker on my own work as well. I rather put my own thoughts out there than go down the shameful road of stealing someone else content.
