Pesquisas do Google nos meus logs de acesso do Apache?

Question

Estou bastante familiarizado com a ideia de que bots estão investigando vulnerabilidades em meu servidor, mas hoje, quando verifiquei meus logs de acesso, notei um monte de pesquisas no Google aparecendo nos logs. Qual é exatamente o objetivo disso?

Answer 1

Acabei encontrando a resposta para essa pergunta visualizando várias outras perguntas sobre falhas de servidor de natureza semelhante e, em seguida, pesquisando no Google, encontrei o seguinte:

http://wiki.apache.org/httpd/ProxyAbuse

Answer 2

Isso não é Google. Quem está acessando seu site está solicitando a página chamadahttp://www.google.pl/search?q=some-query

Execute um whois no ip solicitante e você obterá isto:
