Thanks for pointing this out. When looking in the past on sigs, via
WWW key servers i always had the impression that people do a lot
of "fan" signing, thus making the classical WoT somewhat untrustworthy
to me, because those fans have never met you or others in person.

Should we ever see a new key server model, replacing the current one,
and only owners can upload their keys i think this would help to
eliminate those fan sigs too, which IMHO have no weight, unless of
course the owner of that key with fan sigs would also verify and sign
those signers.

Maybe a sig4 = family, long time friends which does not involve
verification of ID card documents. ... :-)
