It is my experience that SEO bots are increasingly ignoring robots.txt entries disallowing them from crawling our sites. Last week we noticed several doing this. I don't mind naming names - semrush, something called grapeshot crawler, something else called blex bot, and moz dotbot. Anyone else having the same experience?
