rejection emails take way too much time to send out but also it does help alot because sometimes a webmaster may be unaware of a problem with there site such has not being able to see a broken thumb when it is cached on the client side.
but seriously to get a rude response when a webmaster is trying to be helpfull to a submitter is just wrong and should be added to the ban list asap.
but i got to give all those a thumbs up
for those that do take that time to notify submitters of there problems.
rejection emails is definitely a privilage.
