OK, so this guy answers with one line, which doesn't answer the question, and is totally off topic. I flag this answer with the option:
This was posted as an answer, but it does not answer the question. It should possibly be an edit, a comment, another question, or deleted altogether.
And then I get the
$title of this question as an answer and -20 flag weight. When I "dared" to post a link as an answer to a question, my answer was converted to a comment, I got downvoted, flamed, etc. When someone posts a single line without any helpful information e.g. "RTFM", this is considered a good answer? Seriously?
Can someone explain to me how is an answer supposed to be removed if not by flagging?
These are links to two of such answers:
