I saw that part of the answers reported in the "low quality posts" are answers that report a command line code, or snippets for a bash script, and some of those answers are up-voted from more than two users, and something they are accepted.
While I understand that the quality of an answer doesn't depend from the number of up-votes it receive, I also think that the community already decided that those answers are acceptable. (Differently, I imagine the community would have voted such questions into oblivion.) The "low quality" algorithm should probably consider that, or the "low quality posts" tab should not show those posts that match some criteria, such as:
- the post has not been edited in the last X days
- the post has not been down-voted in the last X days
- the post has been seen X times
While those criteria could generally apply for any post that is shown in the "low quality posts" tab, I think that with answers containing just code there is few that can be done.
- I cannot add an explanation about why the code works, as I would add something the author of the answer didn't write.
- Adding a simple sentence, such as "You can try the following." doesn't make sense, as it is not actually adding anything useful to the answer.
- Down-voting an answer simply because it contains just code doesn't seem the right thing to do; it could be down-voted if the answer is not correct, but that is what could be done in any case, when an answer is wrong.
