If a query is answered, the user who asked the question can deem it to be helpful/not helpful.
If the issue is solved, the thread will be automatically locked. And no one can necrobump it later on. If not autolocked, the mods can verify the issue to be solved and thread will be locked by them? This would be a hassle for the mods, autolocking feature does help here? This is just a sort of a basic idea. And who knows, this may help stop shitposting same thing over and over again. Maybe even combine this idea along side the merit system. Who knows.
I don't know how bad of an idea this is but I'm just throwing it out in the wild.
This is a pretty good idea but how can the user deem a certain reply helpful? Will there will be an available button or function for members who created a thread so that they can use it to deem a reply helpful then after that the thread will be automatically locked? Another is that, I guess the member who created the thread must be responsible and really used the said function so that we can really avoid more users answering the same thing.
Thinking more about this, it seems like this should only apply to threads that ask for help, like "how to create a wallet?", "how to start trading?" etc. Questions that can be easily answered by a simple solution but if the member who created a thread asking for an opinion on something, then I guess that thread will still come a long way before being locked down.
