This answer only provides a link. As such, it is not unlikely that it will be deleted, and in fact a user has already suggested that the post does not really qualify as an answer (I may presume they also flagged it as "not an answer", but I cannot know that). But the link is actually useful, so deletion may not be the way to go. I therefore flagged for mod attention, with the message
Perhaps should be moved into the comment section. Thanks.
This way, a mod could study the case and decide on whether it should be deleted, moved into the comment section, or let it be. But the flag was rejected, with the message
declined - Using standard flags helps us prioritize problems and resolve them faster. Please familiarize yourself with the list of standard flags: see What is Flagging?.
I really don't get why this flag was rejected. I always thought that this kind of flags are useful, inasmuch as a mod might be able to act before it's too late -- before users vote to delete the post. A regular flag doesn't work, because regular users cannot turn answers into comments. Thus, "mod attention" seems the way to go. In fact, I have raised similar flags in the past (more than a dozen), and they were always deemed "helpful".
Getting a flag rejected is no big deal, but it discourages me from keep on raising them. Are these flags helpful or not? Should I keep raising them?
