However, the reject message is of minimal utility and adds many strings to the protocol which are a common source of vulnerabilities and which wastes bandwidth with no clear gain. I recommend implementations do not implement this, or implement it only for transaction messages (which is the only case that I'm aware of anyone actually using it for something plausibly useful). --Greg Maxwell, 2017-03-14 +
