Today I am doing my achivement 3 post.
That is Achivement content Etiquette.

PLAGIARISM and it's meaning and why it is so harmful ?

Plagiarism means stealing some one others work without getting permission from them and add in your own work.
In another words you can say it that copy some one others work in your own work.
There are many types of PLAGIARISM.
Some of them are :
1.Complete Plagiarism.
2.Direct Plagiarism. ...
3.Source-based Plagiarism.
4.Self or Auto Plagiarism.
5.Paraphrasing plagiarism.
6.Inaccurate Authorship.
7.Mosaic Plagiarism, etc

In complete plagiarism when you complete copy and steal others work without getting any permission from them.

Direct Plagiarism is also same type of Plagiarism in which if you directly copy some one else work.

Self Plagiarism in which user use his own work in different platform, I mean in which user copy his own original work and repost it in Multiple Communities or platforms.

In Mosaic Plagiarism when user use to copy others work some lines or pragraphs in the way and mix in his own work considering it his own work.

Why it is bad act ?

Plagiarism is a very bad habbit, it has many disadvantages. As when you use to steal others work it make you lazy and you can't make progress in every field of life so it is necessary to quit this bad habbit.
And on Steemit if you will do Plagiarism then @endingplagiarism will warn you so don't do this.

If you want to re use others work then you must give source or criteria for this.
Or by giving credit to the owner of that work.
In last I'll say say no to Plagiarism and don't do this bad habbit.
