Unfortunately this is correct. We do use Debians libcanlock but our code
heavily relies on requests to the user database of Individual.NET which
just not exists in the original INN.

But it is fairly easy to implement processing Cancel-Lock/Cancel-Key with
or without using libcanlock. The biggest problem is to guarantee that the
person who tries to cancel is the author of the original article. If you
can't guarantee this, inserting a Cancel-Key is not allowed (and not

Using IP based access control, this is impossible. In all other cases it
could be hard to impossible anyway, so we have to use our database to find
the unique userid of the original article and compare it with the userid of
the cancel posting attempt.
