Would it be possible when someone posts a thread with a title similar to another thread posted in the last 14 days, a page comes up informing them there is a thread that could be similar, with a link to the thread, and then they could click a yes/no box to decide if they want to post the thread

What are the chances of someone using a very similar title though?
