Luigi, that’s kinda harsh. We have been in the affiliate business for more than 5 years now and getting hundreds of emails from programs all the time. I think you should just accept its part of it and definitely not get annoyed by them.
Think of the person on the other side of that email that gets paid for recruiting affiliates, part of the job is contacting people you dont know and that haven’t asked to be contacted. If affiliate programs just sat back and waited for incoming they would never grow.
