No, they take complaints and investigate them.
The license to the public for certain frequencies requires
non-interference, and specifies effective radiated power limits.
The amateur radio licenses aren't to the general public, they're
to members of the public who have passed certain technical
tests... and they also specify non-interference and power
limits.
Your wifi, your microwave, and your wireless baby monitor all
use spectrum that doesn't require a test of the operator, just a
test of samples of the equipment to make sure that they don't
exceed the power limits.
Should any actual installation create inteference and
complaints, the FCC can literally drive vans around your
neighborhood until they triangulate the source, then require you
to stop transmitting until you fix the problem, possibly by
replacing or fixing the microwave oven, and possibly issue a
fine.
