This is related to the following answer, which is a verbatim copy of a text from the source cited at the end: https://math.stackexchange.com/questions/153/what-should-i-learn-first-mathematica-or-matlab/277#277
I don't think it is right to verbatim copy some text as an answer without using a blockquote, or quotation marks, even if the source is cited at the end. Even in that case, I think the answer should be made community wiki, because the author should not gain reputation from it.
Should something be added about this to the FAQ?
