I used to know the reputation is effective indicator for posts to be trending. I didn't understand that how your posts could be subject to plagiarism? They are from your fingers, your life, work, health, problems...
Mistakes that a newbie accont does can be tolerated. However, it can't for high reputated users. I have seen some plagiarism of such users. There is a phrase in my country; "Humankind has sucked raw milk at birht" which means they can do anything bad.
See how I copied that line of yours? If I copy your entire posts and claim them as mine - it is plagiarism.
my posts are not plagiarised - I write everything, all content (including all the pictures) are mine.
Supposing that someone copied your post which is the one about your daily life for example, it would be nonsense.
Yes, but weirdly has happened a few times.
