PSA: Beware of the Necro Threads

[Canadane]

But the problem can stem from the fact that the game has aged 7 years now, much of what has been said about a topic years ago could be entirely out of date. And it often leads to an awkward conversation as people start replying to posts made years ago and will inevitable never get a reply.

The thing with a public forum is you're not directly communicating with people, you're posting ideas or replies for all to view.
People can look upon this information and provide their own input. This doesn't need to have a time limit to it.
Limiting discourse via a time limit doesn't seem like a great idea in any case, especially when people just deem some arbitrary limit to it.
