Feedback loops are one of the ways for reporting spam. Whether and how to provide an FBL is a choice of the MP. End users should report abuse at their mailbox provider's reporting hub, so as to also help filtering. [2] As an alternative, competent users may send abuse complaints directly, acting as mailbox providers themselves.
A draft describing a standard format for feedback loop (FBL) reports was posted by Yakov Shafranovich in April 2005 [1] and evolved to the current RFC 5965. [2] AOL, who pioneered the field in 2003, initially used a different format, and converted to this de facto standard in 2008. [3] Feedback loops don't have to use ARF, but most do.
A consequence of global warming, feedback loops are already making a huge problem that much worse. 'It's already begun': Feedback loops will make climate change even worse, scientists say [Video ...
Electronic feedback loops are used to control the output of electronic devices, such as amplifiers. A feedback loop is created when all or some portion of the output is fed back to the input. A device is said to be operating open loop if no output feedback is being employed and closed loop if feedback is being used. [45]
A vicious circle (or cycle) is a complex chain of events that reinforces itself through a feedback loop, with detrimental results. [1] It is a system with no tendency toward equilibrium (social, economic, ecological, etc.), at least in the short run. Each iteration of the cycle reinforces the previous one, in an example of positive feedback. A ...

In contrast, a closed system uses on a feedback loop to control the operation of the system. In an open system, the output of the system is not fed back into the input to the system for control or operation.
