That pesky Amazon cloud. Maybe a big Bingo. I will remove the blocked IPs from Amazon hosting. I had someone from those IPs slamming Google Ads so I blocked a big range all related to Amazon.
If the problem exists I'll reconstitute the block but for now let's see if removing them helps.
OK - I removed the motherload of IPs and I will come back and respond to the result after about 48 hours or sooner if I see positive results.
UPDATE: After removing the blocked IPs the site was crawled the max 10K pages.
UPDATE 2: The Adsense slammer returned under several different Amazon Cloud IPs so I had to block the full range again as I don't want to get banned by Google. No money registered only numerous ad clicks. This is unacceptable so I won't crawl this site.
Thanks,
Don
