Today I got this review, and read through it. The already marked reason for closing, was to close it based on the "problem went away because of a typo", which—looking at the comments—seemed reasonable.
Before voting to close however, I took the time to look up the Linux Mint releases information to be able to provide a link, in a comment, asking the OP why one would want to install a version of Mint for which support ended in May 2014, intending to point out the risks of doing so in the comment. Only after looking that up did I see that the post for review was from 2013, which made making such a comment kind of inappropriate.
Recently it looks like some background process digs up such old posts for review, or else it seems that someone systematically goes over older stuff. That is fine, and I don't mind doing the reviews as they trickle in, but it would be nice to have some banner more clearly indicating that these are old posts brought up for clean-up. Assuming some automated process inserts these old posts in the review queue, can we get such a banner?
The alternative is that I constantly put up my glasses while reviewing. The low contrast light-gray colored date information (on a light-blue background) is just beyond the edge of what I can comfortably read on my computer screen with my old eyes. (Normal black on white text I can still read, but for how long?).
