To help anyone else, AMAZON have sent me responses to the effect that the EC2 server was misconfigured. IP addresses are not resolving properly. This only happens from a hacker or criminal employee. They stopped the yelp spam in its tracks eventually after I abused them with vile language and they responded telling me they won't help me and then I bombarded them with all my spam headers and they apologised and shut up. Means they don't stop spam if you don't harass them. I also have a singlehosti.com, itlgopk.uk, rf-cheats.ru super spammer. What started to happen is the spammers started altering their headers to stop getting triangulated. Most of these were coming from AMAZON but not all. I remembered that years ago I tried stopping this one and got more spam. I reported it back then but nothing was done about it. Now after shoving it down their throat and asking why the fu** they don't parse every part of a header and make sure all domains aren't fake before forwarding the email as I received over 400 spam in less than a month using the same spoofing domains and tricks again they stated EC2 corrupt configuration.
The spam is slowing but goes through increases when the spammers are trying to find who is pinning them down. To my comments above use spamcop and abuseipdb. Be careful with abuseipdb as if you put too much info in the spammers can track the complaint source. Exclude and numbers or generated alphabetic scramble. The pricks looked at the country of complaint and started trying to fu** my countries AMAZON server. Use CHROME incognito to assist hiding your location. Not very good but safer than all other browsers. Most of the spam is rf-cheats.ru and uses the singlehosti.com and itlgopk.uk domains in their headers frequently with some others such as raynair, goodridge and a couple more. It takes time initially but is worth it. The bad AMAZON servers are mainly Israel (top), Germany, France and Japan. You can include Portland and Virgin Islands in the US.
The AMAZON spam is slowing but AMAZON is hiding their incompetent systems that have most likely been hacked with a mail scri_pt to hide the spammers trail.
To any noobs, UNSUBSCRIBING from spam gets you more spam. I have read that some people think this works. It does not with real spam. Do not confuse unsubscribing from legitimate newsletters or promotional material as an answer. You must report the spam. spam is spam and you have rights. It will mentally get you and you will never have mental peace and if you get this and it is a lot to move all your stuff to another email address then get to it.
You will find the spammers send messages in their spam if they think they have trumped you and also if you have pulverised them. Its a bit sad really but if you don't be vigilant for a few months it will get worse.
At this stage I have them on the run and want all you people to help squash this sh** and the owners. They are vermin.
