No torque mechanism studied supplies enough angular momentum for the innermost light-PBH shells around a heavy seed, so the spike core is swallowed and far less dense than a WIMP spike.

Microlensing surveys constrain fast and slow compact objects at masses and densities differing by orders of magnitude from dark matter limits due to speed-mass degeneracy in Einstein crossing times.
O4a gravitational-wave data give 95% CL upper limits f_PBH ~ 1e-2 to 1e-4 for monochromatic primordial black holes with mean masses 0.6-100 M_sun, with no evidence of a PBH merger component.
LOFAR2.0, FAST Core Array and BINGO are forecast to bound f_PBH < 0.16 (M>1 Msun), <0.39 (M>10 Msun) and <0.39 (M>0.1 Msun) respectively from null FRB lensing.
