Hi there, I wanted to report some aggressive crawling by the bot with the user agent
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/600.2.5 (KHTML, like Gecko) Version/8.0.2 Safari/600.2.5 (Amazonbot/0.1; +https://developer.amazon.com/support/amazonbot)
It seems to be a bot by amazon but I couldn’t check the originating IP addresses to confirm that.
This is what the last 5 days look like:
For comparison, this our user agents table for the last two days. 39649 vs 457
I personally don’t care too much about this as we’re not the ones doing the hosting and we haven’t noticed performance issues but CDCK is. So I figured this could be interesting to share here.
From our site and container logs it appears that there was a spike only that particular day and only on that site

I see. Thanks for checking it. Probably a technical user, having a bad day and making a trashy bot to target our website with no effect. We’ve since blocked that crawler.
Fico muito feliz que a Alexa possa usar o conteúdo do meu site para responder perguntas, então eu realmente não quero bloqueá-la. No entanto, acabei de ver um pico de três dias de tráfego intenso do AmazonBot (em relação a todo o outro uso do site, incluindo todos os outros bots combinados, bem como todo o outro tráfego do site em geral), e vejo que a Amazon diz:
O AmazonBot não suporta a diretiva crawl-delay no robots.txt
Portanto, parece prudente adicionar Amazonbot a slow_down_crawler_user_agents para que eles não tenham um impacto desproporcional no desempenho do site para os usuários.
Obrigado, pessoal do Discourse, por implementar funcionalidades que os rastreadores deveriam ter, mas neste caso não têm.
