Recently I've seen questions that are quite old (1-5 years) suddenly appear on DIY recent questions. I don't seem to be able to close them as "late answers" , maybe I don't yet have enough reputation points to do that, but that's not the issue. The issue why did this suddenly start happening?
Here is one example posted earlier by FreeMan, apparently he's experiencing the same thing. I'll edit and post more as I run across them.
What to do with new answer to old questions when they don't add anything new?
Just ran across another one: Need help identifying the manufacturer of a frost free anti-siphon faucet.
