I’m getting annoyed with people that ask a question, have the community answer their question and troubleshoot over several days, only to delete their post and the solution.
The person asking the question is often providing the least amount of effort, so why should they have exclusive right to delete the contributions of others?
Possible fix: have a per-community option to only request deletion.
I think it should have to go through a mod. You can publicly hide your name from the post (it still needs to be visible to mods for moderation purposes), but you should be have to ask a mod for total thread deletion.
Although that may not be the answer either, someone pointed out apparently mods are nuking threads too???
