as written in the proposal
key 8B5A ABB1 A033 21CE C2FF C35F 3BA0 E844 EDEB DFE9
is a faked key which is signed by a faked CA.
THAT's exactly the problem I want to fix!

And note that for ordinary users it is not that easy to find out
Yes, people could in this case double check with the web site of
the magazine. But they simply don't do that (including me and
a couple of other people here in this forum!).
As a result Jürgen aganin and again gets emails with the wrong key.
And I dind't get an answer from Jürgen ...
And ...
I want to avoid this unnessecary burdon.

BTW, as another example,
several keys of team at are faked
(search for these keys and the the interesting result).
