I ended up blocking Amazon SES because I was receiving hundreds of obviously spam emails across all my inboxes every day for weeks. I dutifully sent multiple reports of this obvious spam to the listed spam/abuse contacts for Amazon SES.

The end result of my efforts was:

  1) No feedback at all from my reports to Amazon - not even an acknowledgement that my report had been received
  2) The spam continued unabated for weeks until I finally had enough and just blocked the entire Amazon SES service

That was a few years ago and maybe they are more responsive now. They sure as hell weren't responsive back then.
