Question and suggestion about the Trucking Marketplace

I see threads in that forum that initiated several years ago and the OP never posted what happened with the deal. Some sellers may have sold what they were advertising or changed the info in their thread, some buyers may have found what they were looking for but nobody ever posted what happened and the threads remain open, causing potential buyers to visit a thread when the product is no longer available. Or causing buyers not to return to a thread they have visited before for thinking they already know what it is in it.
And if the seller needs to update the info on their thread, he/ she will have to create a new one just for that.
IMHO that causes an increase in threads that are outdated and no longer relevant and/or the creation of new threads just for the purpose of changing the title and the info on a thread that is still open.
I would like to suggest all threads on that forum to "expire" after a certain amount of days or weeks unless there's some communication between the OP and the site to keep it open for another "round".
There would be a notice when someone tries to start a new thread in that forum advising them about this rule. And maybe also a notification to the OP a few days before their thread is closed and deleted telling them that if they want it to remain open, to let them know.

Would like to know what your opinions are. Thanks.
