I like this idea. It is worth trying; the main problem is getting
someone to implement it. So one should strive for a plausible
I don't think the quoting issue is a big problem; authors who don't
quote enough won't be understood, and authors don't like that.
Similarly while a per page or line charge might be best, a per post
charge seems workable and much simpler; overly long posts will not get
A non crypto first implementation also seems fine. Just go down the
subscriber list at some rate sending out random ASCII strings of
length 30, which people can forward to whomever they like. The big
problem is not people stealing tokens from peeking at messages; it is
people creating new addresses to get more tokens. So I suggest tokens
only go to subscribers who have posted to the list within the last
month (or three months?), with the first post per such period being
Having tokens expire after some period might be more robust to dealing
with unknown accumlations of tokens. Then it would be fine to have a
target number of posts per week, and use a one or two week moving
average of the recent posting rate to adjust the rate of token
The token for a new post should probably go in a special header line.
