Or we can use the same logic that the Clapper and Alexander use. Instead of the canary, just publish a database containing a list of the NSLs. Distribute a client that syncs the database, and disallows logins if your user is affected. Politely ask that your users not attempt to view the information in the database that has been sent to them periodically.

Since no human actually read the contents, they didn't "collect" your communication, so you haven't broken the law.

Remember, they themselves set the legal standard so that you can have all of the data you want, but it doesn't count as you officially having it until you actually look at it!
