I’ve been thinking about this for awhile.
In some cases, locking the thread is a good thing. Eg on one of the database forums I frequent, they did this. This feature prevented old/no longer valid information from surfacing.
But, it could be a bad thing. Eg that forum also locked user generated FAQ/Wiki pages that could no longer be updated with new information.
Additionally, the fix may have to apply to the forums of other games.
My suggestion
- A “did you look at these threads?” algorithm is used
- For older posts, something that verifies that the poster really wants to necro a thread. (Captcha?)
