In my database I have a number of types of data, many of which are 'deletable'.
When a user deletes content I store the date of the deletion and purge content that was deleted 30 days ago - This means my support team technically can restore content if users really need it, or eventually we can allow users to restore their own content.
Given this, is it more annoying to confirm with users if they 'really want to delete' content if the content is only 20 minutes of work or so than it's worth? They'd have to at the least ask someone else to restore the data, or worst case would lose it permanently.
It's more of a poll question, or one that could really use some real user data, so if anyone knows if information on this has been collected before, that would be great.
