The Roomba process eliminates closed, negatively voted, etc. types of questions after weekly, monthly, yearly checks. However, I do not understand why the similar checks are not applied to answers.
For example, if today I google for "Is the t-butyl carbocation more stable than the benzyl carbocation?", I would get this Chem.SE hit. Now, obviously, my query is answered in the accepted answer, as well as the other two answers, but why is the fourth answer left there for me to see? It merits deletion, because it is:
- negatively voted: indicating that it is low quality or clearly wrong
- abandoned: user has not shown effort to improve it, it was last edited four months earlier
You can see a similar case here, and in many other questions on many other SE sites.
My question remains the same: why aren't old, abandoned, negatively-voted answers auto-deleted? Clearly they don't add any value to that question, so why not delete them?
(I have tagged this discussion because I am interested in the philosophy behind the decision; however, if multiple users agree on the fact that such answers should be deleted we, may edit this into a feature-request)
Dan made a point that "negative scoring answers are useful as a signal of what’s known wrong." However, consider that negatively voted answers are already greyed out below a vote threshold. So, it's clear that the admins at SE don't want us to read them.
That, and if there's any topic where a concept has a possible pitfall, it should be made clear in the answer, in such a format: "This is a popular pitfall: ... Why people think it's correct:... Here's why it's wrong" so that it adds more value to the question. The current trend is mostly a bad/wrong answer and then discussion/argument in the comments about its incorrectness, which does not help future readers.
