On multiple occasions on our forum, we’ve had someone post something that has already been addressed/answered, and another user responds to them. For instance:
“You can re-open tabs on Chrome by pressing Ctrl+Shift+T”
-> “OP already said this was incognito and wouldn’t work”
When the first user deletes their post to clean up the thread, after 24 hours the second user’s post looks weird. Ideally they’d withdraw their post as well since it is no longer relevant, but they never know the prior post was deleted. If users received an automated notification whenever a post they replied to is withdrawn or deleted, they could act on their own post.
I’m not sure whether on withdrawl/deletion is preferable – withdrawn would allow for chains to be cleaned up more quickly, but withdrawls can also be reversed. I could maliciously withdraw my controversial post, get someone to withdraw their reply to me, and then reinstate my own post now free of criticism. Is this a legitimate concern? Would we need to notify when posts are reinstated as well?
