The rule-> "33. Posting plagiarized content is not allowed.[e]"
Plagiarism
"an act or instance of using or closely imitating the language and thoughts of another without authorization and the representation of that author's work as one's own, as by not crediting the original author:"
-> Rule explained "33. This includes both copying parts or the entirety of other users' posts or threads and copying content from external sources (e.g. other websites) and passing it as your own."
So in other words: This would imply to take credit as your own from someone else's work... not actually failing to put "quotes" on your pure intent of informative post or rather forgetting to link the source. To take credit and to make credit, thus to give credit; it can mean a much broader idea then its objective one.
It does not make sense to take an objective idea and transform it into subjective one, commons sense also prevails
For example, i can say "don't drink water, because you die!" Does this make sense? No, of course you don't die... But, i would prove you wrong, subjectively speaking, because it is forming my own concept of what i would say: drinking too much water in some cases can make you die (and now this is a true statement). See the difference? That's why we would need someone to defend us and our rights...
You broke the rules 2 times yourself. You quoted, but you didn't mention the source.
