I ask, just as the bot detects when there are new posts, isn't it possible to have a bot that detects edits? I know these are different things, but the forum, after an edit, leaves a record in the post that it was edited. Isn't it possible to check this information?
New posts
are easy to find, edited posts can be anywhere in millions of topics and tens of millions of posts. At no more than 1 page request per second, it takes months to check everything (again).
