Recently, I found a spam "question": stimulating the original collagen and elastin development (mirror for non-10kers)
It had -1 votes, 2 views and was asked about 2 minutes ago. I, of course, flagged as spam. But what I saw and really got me was:
I'm voting to close this question as off-topic because it's spam - A 5k user
I don't remember all the details (like the time that the comment was posted) and the question is long since deleted. But the main part is that this isn't a good action. (Just to prevent any misunderstanding, I'm not against that user in any way; I don't even know him.)
Instead of flagging the question as spam, the user voted to close the question. Why I see this wrong:
This just delays the deletetion of the question. If the question had to be first put on hold, then closed and then deleted (everything by voting), we would have every spam post around here for a week or more - that's bad.
Flagging as spam is the fastest way of getting the question deleted, and the user too if he's new. After a spam "question" is flagged 6 times as spam, it will get automatically deleted.
Here's my point: Please do not vote to close or vote to delete spam questions. It just slows things down. Just flag it and go away. As for me, I don't even bother to downvote.
Please use this as a reference point to any user, who would vote to close similarly.
