* Don't delete the user's favorites unless private favorites are enabled. The general rule is that public account activity is kept and private account activity is deleted. * Delete the user's API keys, forum topics visits, private favgroups, downvotes, and upvotes (if privacy is enabled). * Reset all of the user's account settings to default. This means custom CSS is deleted, where it wasn't before. * Delete everything but the user's name and password asynchronously. * Don't log the current user out if it's the owner deleting another user's account. * Fix #5067 (Mod actions sometimes not created for user deletions) by wrapping the deletion process in a transaction.
