Sounds reasonable to me.
Tdma for personal email protection is rude and unacceptable. For mailing lists it is entirely acceptable. Cost far outweighs benefit as the inconvenience to the single sender is much less than the benefit to the community.
Should also consider if spf or dkim checks could cull the paypal spam.

Subject: Spammers answering TMDA Queries
The Secretariat tells me that Spammers are responding to TDMA queries
so that their mail goes through. They have made the suggestion that
we clear the list of people once per year. This would mean that a
legitimate user of a list that uses TDMA would get a TDMA query once
a year if they are not subscribed to any ietf.org mail list. There
is no TDMA query for people who are on at least one ietf.org mail list.
Here is the info that I have:

Thoughts?
