Since you are from Sweden, and in an IT job, you probably have personal
relations to someone who has personal relations to one of the swedes

(which -- because of the above -- should be doable OOB quite easily for
you) you can start validating the entire chain of trust.

Quite trivial, in fact.

I'll note that the PGP "strongly connected set" has grown all the way to 45,000
or so keys in 2 decades of growth.  There are several billion Internet users. What
may be workable for Fredrik is probably *not* scalable to Joe Sixpack.
