Today, a friend of mine had trouble using Eclipse with JDK 7 on her mac and I recommended that she search StackOverflow for a solution. She successfully located a post that described her exact problem, but the solutions posited by the answers did not help. As she was having exactly the same problem as described in the post, it did not seem appropriate to ask a new question. However, my friend lacked enough reputation to post a comment (and knew better than to post an answer). So, knowing that her comment was constructive and appropriate, I logged in and allowed her to post a comment using my account.
While I can understand why this kind of behavior might be frowned upon in general (as it violates the idea of reputation unlocking principles), I reviewed the comment beforehand and deemed it acceptable. The point of reputation-based privileges is to prevent users who don't know (or don't care) how to properly use the site from cluttering it with irrelevant, fraudulent, or otherwise unwanted content, but I asserted that this was not the case.
From the tag wiki:
"The reputation is a measurement of a user's contributions to the site, and the extent to which the community "trusts" that user with extra privileges."
The community may not trust my friend yet, but they trust me enough to make comments. Therefore, I figured if I thought the comment was good, it was acceptable.
So the question is: was I violating any sort of community rule when I allowed my friend to post a comment using my account?
For the record, the comment in question is here.
