Octocular's core spidering functions were carefully tested during October and November 2012 and you should find it to be a well-behaved visitor to your site. If it causes any problems, or you just want to talk to the owner, please use the email address below:
Octocular understands robots.txt files (including the crawl-delay directive) and should obey them except when performing anti-malware scans. Changes to robots.txt will usually be applied within 24 hours. Default crawl speed varies by site but it's usually a very polite one request every 1 to 15 seconds.
