The codepoints being abused are TCP options.

Those options are assigned for IETF standards. There are two current abuses:

	- self-assigned (squatted) codepoints 

	- widescale deployment of experimental codepoints

See draft-ietf-tcpm-experimental-options-06 for a solution to the latter, and a summary of examples of both.

These have been *entirely* avoidable. The new method lowers the bar for experiments, though they should still not be deployed into the wild without monitoring.
