get junk mail, take a picture with the app they remove you from that retailer

"While the app-specific code is a good idea for a first line of defense against spam, you should still implement some rate-limiting on any services you are concerned about.

For example, if you use sessions on your REST services, you can easily rate-limit the number of calls you process from a single session. The session doesn't have to be authenticated at all and is only used to identify a single client while they are making requests. A simple redirect back to the requested service if they try to connect without an open session is all that's needed, and virtually all web frameworks or stacks have this built in.

You can also rate-limit on other properties, such as IP or user-agent fingerprint, but those are less reliable than a session-based method."

"With CAPTCHA’s on, SPAM and failed conversions accounted for 7.3% of all the conversions for the 3 month period. With CAPTCHA’s off, SPAM conversions accounted for 4.1% of all the conversions for the 3 month period. That possibly means when CAPTCHA’s are on, the company could lose out on 3.2% of all their conversions!"

"lets an organization take responsibility for a message while it is in transit.  The organization is a handler of the message, either as its originator or as an intermediary.
