Identification
Its full user-agent string, exactly as it arrives at the gate:

How to block YaK
Add these two lines to the robots.txt file at the root of your site. Well-behaved crawlers read it before they crawl, so the change applies from YaK's next visit. Nothing else on your site needs to change.
# Block YaK from the whole site User-agent: YaK Disallow: /
Or let it visit but keep it away from part of the site:
# Let it in, but keep it out of one room User-agent: YaK Allow: / Disallow: /members/
