Another option involving scraping, but allowing some human intervention, would be to have a default title - and have a new, and optional "edit the title" page for submitters. This would hopefully decrease the number of edited titles as they would be more effort to enter - and would let the mods revert them with the click of a button as they could compare titles without reading articles.
