I wish to make the site look better for everyone. So I vote to close some questions that deserve it. And I flag as very low quality when I'm out of close votes, hoping that the others would vote to close/delete it instead.
Recently almost all my flags were declined with the following comment:
declined - if you think a question should be closed, please use your votes
And sometimes, even when I flag a question with -5 votes as very low quality, I get this response:
declined - a moderator reviewed your flag, but found no evidence to support it
What evidence should I provide? Isn't the question itself the evidence? It looks off-topic and terrible. Also usually have negative score.
Update (30/5/16): I now have a gold Marshal badge, thanks to my improved flagging behaviour! Now I'm one among the 21 users so far to have ever received it on ELU. :)
