There are always people around who tend to pretend to be you or/and attempt to steal your work online. They will try to be you and claim your work as your own or worst of all erase it's watermark entirely. To me this is probably the most despicable thing i had ever seen where someone take your hardwork where you had poor blood, sweat and tear intonit and they simply just take it and claim it that it's theirs.

This is a shout out to all artist and writer out there. Watch out for this type of people online as they do exist. (I had reccently seen one personally) Don't fall prey to plagiarism.

As for those who plagiarised other people work or impersonate them. You can't hide forever as there is such thing call copyright. Even if you want to share the work always give credits to the original artist or writer.
Don't be a jerk. If you are pretending to be someone else stop it as well as you are ruining the original artist/writer reputation.
