Why do you think this can not be considered plagiarism ?

It was an exact copy/paste of the post of another user.
You didn't forget to quote it properly, you didn't express any opinion. You simply just copy/pasted it.

If you just wanted to help someone / answer questions, why not either just quote it or use your own words ?

I don't think this falls under the category of mistakes mentioned by theymos.


IMO this is very clearly plagiarism.. anyway.. i wish you good luck getting your account back.
