How can I check if something has been posted before, to avoid double posting?
The New Post form will automatically check for you. Just enter the URL and click "Preview."
For better searching, leave off everything but the domain name -- no "http," no "www" and no directory or html suffix information. This makes it more likely the search will catch a double.
You can also plug a URL into the Search box on any page, or search in Google by pasting the URL into Google along with this string: site:www.metafilter.com (tags: doublepostURLsearchmetafilterlink ) January 25, 2013 - permalink - back to questions
What is double posting? Is there a statute of limitations on double posting?
A double post is when someone posts something to the front page of MetaFilter (or sometimes MetaTalk) that has been there before.
There is no hard and fast rule on when a post is not a double anymore. For an identical URL and a site that hasn't changed in content "a few years" is a good guideline. For a site with the same URL and new content, indicating the previous post in your new post is a good idea. If there is a post on a similar topic still on the front page, please post your link into the open thread instead of starting a new post.
With few exceptions, there is no such thing as a doublepost in AskMe although users should generally search prior questions before posting to determine whether a very similar question has already been asked and answered.
