Citing and reproducing content from other websites is different from copying an answer wholesale from somebody else.
We have some explicit guidance on how to reference material written by others in the help center.
I'll call attention to this line:
Do not copy the complete text of external sources; instead, use their words and ideas to support your own. And always give proper credit to the author and site where you found the text, including a direct link to it.
(emphasis not added)
In the answer that you provided, you took three Reddit posts, slightly edited them, and posted that as an answer. You did provide links to the original source, which is good, but the answer failed on a couple things:
- The entire answer consisted of copying from from another site
- You are potentially putting words in other peoples' mouths, as you say that you are quoting, but then don't use quote blocks and have claimed to have edited the text.
On this site, we generally discourage answers that just provide a quote - especially when that quote can be found elsewhere on the internet. We expect answers to provide an explanation of what they are quoting. We expect users to not copy the entire text of the sources; it says so quite explicitly in the help center page ('Do not copy the complete text of external sources;').
While using a post on the Internet as the basis for your answer is fine, you shouldn't just quote that and leave it at that. Quote relevant portions, but actually answer the question in your own words. Don't just take credit here for what someone else wrote on another site. Instead, use their post as a starting point for writing your own answer, and write an answer that uses that as a source.
I'll quote this line from Robert Cartaino, from a comment on a now-deleted post:
The purpose of creating this site is to curate a collection of knowlege[sic] for the folks searching for this stuff. Please do not simply duplicate content that can already be found elsewhere. Posts that are copyied[sic] almost entirely from external sources are not considered an answer in the context of this site.
If someone searched for
what is post-modernism in literature, and they find the Reddit posts, then they have what information is included those Reddit posts. If they then find Literature.SE, and find that exact same information, phrased in the same way, then this site isn't being helpful. We should strive to provide better, more complete answers than other corners of the Internet. This means that we shouldn't be copying posts wholesale that can be found in other places. We should be providing high-quality, original posts.
I'll also point out that when quoting from a source you should use quote blocks, for one thing, and when making a change to the text, clearly mark what you changed. If you're adding words, you can add brackets around your addition, sort of like this:
Citing and reproducing content from other websites, appears allowed [on Stack Exchange]? See https://math.stackexchange.com/search?tab=votes&q=is%3aanswer%20reddit.
Or, if you believe that the original text has an error, you can add a [sic] in the quote... like I did when quoting the comment from Robert Cartaino above.
If you make any change to the text you're quoting - including spelling fixes, emphasis, and anything else - you should mark that clearly.
So - when writing a post, please don't just copy from another site. Instead, use that site as a source, and write your own answer.
