You can't steal someone elses work and try to pass it off as your own.

Not indicating that the content you copy/paste is not your original work could be seen as plagiarism.

Some tips to share content and add value:

• Use a few sentences from your source in “quotes.” Use HTML tags or Markdown.
• Linking to your source
• Include your own original thoughts and ideas on what you have shared.

Repeated plagiarized posts are considered spam. Spam is discouraged by the community, and may result in action from the cheetah bot.
