This is how things always worked well.
If one sends too much, you just stop reading and let the lower layers
take care of throttling.

Isn't that throwing responsibility on the victim?
It should be the aggressor, that takes consequences of the action
(finding out the abuser).

What I'm afraid of, is if we encourage taking care of abuse at the
passive (receiving) side, that cannot take real action on the abuse, the
active (sending) side won't ever implement efficient way of preventing
abuses, relying on the reports from victims. (Similar to what is
happening in the SMTP realm with SPAM)

- "Oh, this user is abusing you? I'll disable his account."
  "And this one now? I'm disabling it now."

instead of proactive:
- "My users are abusing you and you throttled me? Oh! I will find out
the responsible ones. And will take actions to not let it happen again,
cause this is hitting all my innocent users."
