While I have a lot of sympathy for the cause, I have very little
sympathy for the methods.
Rendering a mailing list that might be useful for actually resolving
the issue inoperative by a "campaign" is idiotic.
Somebody from I* (the IETF chair may not be the right person this

friends and impress people.
PS: kill-filing messages CCed to campaigns(_at_)ietf(_dot_)org might help a bit.
I don't know if the procedures allow to do this at the mailing list
