Thank you for bringing this up @crypto.piotr.
Plagiarism is not accepted anywhere, especially when one is trying to make earnings with it.
That being said, posts are easily written when you are writing from personal experience. However, I will advice everyone to do a thorough research when writing about a topic that is not from personal experience. When you do a research and fully understand what you're writing about, you can easily write in your own words, instead of spinning someone else's words, or copying and pasting verbatim.
