In the “older days”, this method was quite adequate for the electrical
loads being produced in a house hold. However as computers, plasma
TV’s and microwaves became the new way of life, the increase is
amperage (electrical current) to run these devices posed a problem for
knob and tube wiring. It became subject to repeatedly blowing 15mp amp
fuses. Quick fixes allowed homeowners to over-fuse circuits (changing
the 15amp fuse to a 20 or 30amp fuse) which in turn caused heat damage
to the wiring due to higher levels of current.

The only K&T hazard in the post - as already stated, over fusing can be
a problem for any wiring system. This is not a specific K&T hazard.
