  The most distant AGN, within the allowed GZK cut-off radius, have been
recently candidate by many authors as the best location for observed UHECR
origination. Indeed, the apparent homogeneity and isotropy of recent UHECR
signals seems to require a far cosmic isotropic and homogeneous scenario
involving a proton UHECR courier: our galaxy or nearest local group or super
galactic plane (ruled by Virgo cluster) are too much near and apparently too
much anisotropic in disagreement with PAO and TA almost homogeneous sample
data. However, the few and mild observed UHECR clustering, the North and South
Hot Spots, are smeared in wide solid angles. Their consequent random walk
flight from most far GZK UHECR sources, nearly at 100 Mpc, must be delayed
(with respect to a straight AGN photon gamma flaring arrival trajectory) at
least by a million years. During this time, the AGN jet blazing signal, its
probable axis deflection (such as the helical jet in Mrk501), its miss
alignment or even its almost certain exhaust activity may lead to a complete
misleading correlation between present UHECR events and a much earlier active
AGN ejection. UHECR maps maybe anyway related to galactic or nearest (Cen A,
M82) AGN extragalactic UHECR sources shining in twin Hot Spot. Therefore we
defend our (quite different) scenarios where UHECR are mostly made by lightest
UHECR nuclei originated by nearby AGN sources, or few galactic sources, whose
delayed signals reach us within few thousand years in the observed smeared sky
areas.
