I've bumped into a question that is 2 years old, has 0 score and is off-topic (question about 9.10 asked 1 year after EOL).
I flagged it off-topic by instinct, but it is a good practice to do this?
It's extra work for someone to review, but I guess it helps to keep the site clean. Or am I just too pedantic here?
Edit: I'm rather new on this site, but all of my flags were found helpful so far. I'd like to keep it this way, hence the question.
