Grave Digging Older Threads

I have a suggestion. I've noticed many threads/topics that were made on the forum are very old and haven't been locked. Threads from 05' that are simple questions are being brought back up to the top with people answering the Original Poster's question. Not only are they answering it, they're answering it as if the original poster just posted it yesterday. Now I can't speak for the original poster, but I'm sure he/she doesn't need this information 7 years later...
That's a whole different story if the topic is still relevant/informative. Which could easily be made a sticky.

I just think topics that are THAT old, should be locked and left alone to drift to the bottom, where if people need it, can still search up information on it in the search bar.
If for some reason this particular topic needs to come up again, someone else can start a new thread on it, and at least there can be fresh, up-to-date information given.
