Does blocking us on this basis make any sense?
Blocking because a system/netblock has made many attempts to send to non-existant users makes sense.
Any single address from wich a certain number of such attempts is done during a the last n minutes are blocked with a tenporary failure here. Netzero might well be doing something similar.
Of course it is also possible that they block in a way that doesn't make sense.
Without knowing what your system(s)/netblock did to their system(s), what made them block you, and how long the temporary period is, it's impossible to judge wether it makes any sense or not.
