I have realize it after I read this topic since mid-April, and of course the policies taken by the admin according to the expected standards are worth the time.

For me 6 months is not a short amount of time, so it should be long enough to mark an old post that may not be worth reporting even if it's only for the purpose of reducing forum spam. Something dangerous is still expected to be reported even though it was made years ago and only recently discovered, and I think the moderators will handle it well.
