I got to review an edit today that wanted to add a citation to an answer. Said answer was a verbatim copy of a program from another website, without citing it. I went and checked it out and it was true. (I've obviously accepted the edit but it hasn't gone through yet.)
Is this allowed (i.e. copying a program from a site and posting it as your solution)? Is there a policy on this? I've searched on meta but couldn't find anything.
While I'm at it, how should people go about posting stuff from other websites (if at all)? It could be relevant from time to time. (i.e: this person on that site has done this better than anyone can: like so).
(I don't really want to call out anyone and I'm new to meta so I've not posted a link, will post the link if you guys want me to.)
